    Perovskite crystal grain size control, grain boundary passivation, and grain bridging are the keys to obtaining high efficiency in perovskite solar cells. A small amount of semi-conducting single-walled carbon nanotubes added to a perovskite active layer can achieve this. In particular, the surfactants attached to the semiconducting single-walled carbon nanotubes a crucial role. In this work, we synthesized a new surfactant, 4,6-di(anthracen-9-yl)-1,3-phenylene bis(dimethylcarbamate), which has a polyaromatic group on one end and a urea-analogue carbamate group on the other end. The polyaromatic anthracene end functions as a nanotweezer clenching the carbon nanotubes strongly via pi-pi interaction while the carbamate end interacts with Pb2+, functioning as a strong Lewis base. In addition, the new surfactant has conjugated double bonds with a suitable bandgap, resulting in enhanced charge mobility in the perovskite film. Overall, the new surfactant-clenched semiconducting carbon nanotubes showcase superior effectiveness as passivators and charge bridges in perovskite solar cells as compared to the conventional deoxycholate surfactant-wrapped semiconducting single-walled carbon nanotubes. The new surfactant-attached semiconducting carbon nanotube-added NH3CH3PbI3-based perovskite solar cells exhibited a power conversion efficiency of 20.7%, which is higher than that of the reference devices with no additives (18.4%) and the previously reported semiconducting single-walled carbon nanotube-added devices (19.7% in this work and 19.5% in the literature).

It was found that the calculated intermolecular interaction energies corresponded to the solubility measured by UV-vis spectroscopy. This correlation was consistent with differences in substituents and in the metals in the porphyrin core. </jats:p>

    © 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Double-walled carbon nanotubes are between single-walled carbon nanotubes and multiwalled carbon nanotubes. They are comparable to single-walled carbon nanotubes with respect to the light optical density, but their mechanical stability and solubility are higher. Exploiting such advantages, solution-processed transparent electrodes are demonstrated using double-walled carbon nanotubes and their application to perovskite solar cells is also demonstrated. Perovskite solar cells which harvest clean solar power have attracted a lot of attention as a next-generation renewable energy source. However, their eco-friendliness, cost, and flexibility are limited by the use of transparent oxide conductors, which are inflexible, difficult to fabricate, and made up of expensive rare metals. Solution-processed double-walled carbon nanotubes can replace conventional transparent electrodes to resolve such issues. Perovskite solar cells using the double-walled carbon nanotube transparent electrodes produce an operating power conversion efficiency of 17.2% without hysteresis. As the first solution-processed electrode-based perovskite solar cells, this work will pave the pathway to the large-size, low-cost, and eco-friendly solar devices.

    High-performance air-stable PBTZT-stat-BDTT-8 organic solar cells were fabricated using mixed C60/C70 fullerene acceptors. Normal-architecture devices using PBTZT-stat-BDTT-8 with PC71BM produced a power conversion efficiency (PCE) of 9.38%. An inverted-architecture, which possesses higher stability, was fabricated using a more economical PC61BM and PC71BM mixture with solution-processed PEDOT:PSS on top and produced a PCE of 8.15%. Exploiting the viscous nature of PBTZT-stat-BDTT-8, the slow evaporation effect was utilised to achieve an even higher efficiency of 8.73%. A stability test was conducted under operating conditions and our devices showed remarkably higher stability compared with PTB7-based devices.

    A diphenylanthracene dimethylamine derivative (9-{3,5-di(N,N-dimethylaminoethoxy)phenyl}-10-phenyl-anthracene, DPAMA) was synthesized by the Suzuki-Miyaura cross-coupling reaction. Its ammonium salt, 9-{3,5-di(trimethylammonium ethoxy)phenyl}-10-phenyl-anthracene dichloride (DPAMA-Cl), was also synthesized as a reference material. DPAMA was characterized by UV-vis and fluorescence spectroscopy, cyclic voltammetry, photoelectron yield spectroscopy, and X-ray photoelectron spectroscopy to evaluate the work function-modifying ability of DPAMA on indium tin oxide (ITO) and ZnO. The work functions of ITO and ZnO changed from 4.4 and 4.0 eV (pristine) to 3.8 and 3.9 eV, respectively. Using this surface modification effect of DPAMA, inverted organic light-emitting diodes were fabricated with device structures of ITO/DPAMA/Alq3/NPD/MoO3/Al (Alq3 = tris(8-hydroxyquinolinato)aluminum
    NPD = N,N′-di-[(1-naphthyl)-N,N′-diphenyl]-1,1′-(biphenyl)-4,4′-diamine) and ITO/ZnO/DPAMA/Alq3/NPD/MoO3/Al. Both devices showed good performance at the range of current density, 1-300 mA/cm2. The best inverted organic light-emitting diodes device showed luminance of 7720 cd/m2, current efficiency of 4.51 cd/A, and external quantum efficiency of 1.45%. Also, poly(3-hexylthiophene):mixed phenyl-C61 and C71 butyric acid methyl ester-based organic solar cells using DPAMA and DPAMA-Cl as electron-transporting materials showed power conversion efficiencies of 3.3 and 3.4%, respectively.

    Promising perovskite solar cell technology with soaring power conversion efficiencies has the common problems of low stability and high cost. This work provides a solution to these problems by employing a carbon sandwich structure, in which the fullerene bottom layer solves the stability issue and the carbon nanotube top electrode layer offers the merits of having high stability and being low-cost. Devices fabricated using different hole-transporting materials infiltrated into carbon nanotube networks were examined for their performance and stability under constant illumination in air. Polymeric hole-transporting layers show much higher stability when combined with carbon nanotubes due to their compact nature and stronger interaction with the carbon network. As a result, the encapsulated device showed high stability both in air and under light illumination, maintaining up to 80% of the initial efficiency after 2200 hours under actual operation conditions. Cost analysis also shows that using the polymeric hole-transporting materials in carbon nanotube films brings the fabrication cost down to less than 5.5% that of conventional devices. Our study proposes a promising cell structure toward highly stable and low-cost perovskite photovoltaic technologies for the future.

    We report mechanochromic color change controlled by conformational change (between folded and twisted conformers) of fluorenylidene-acridanes (FAs). FAs with four N-alkyl groups (methyl, ethyl, n-butyl and n-octyl) were synthesized via the Barton-Kellogg reaction of diazofluorene and electrophilic N-tert-butoxy carbonyl thioacridone, deprotection of the tert-butoxy carbonyl group gives fluorenylacridine, and alkylation on the nitrogen atom is done using alkyl tosylate or triflate. FAs were characterized by NMR, UV-vis absorption and photoluminescence spectroscopy, theoretical calculation, cyclic voltammetry, and powder and single-crystal X-ray analyses. The color and folded/twisted conformation of the FAs were changed by the choice of substituent on the nitrogen atom, physical state (solution or solid), and morphology (crystalline or amorphous). Grinding of N-methyl FA solids, using an agate mortar, caused the morphology to change from a crystalline to amorphous state, which induced a conformational change from the folded to the twisted conformer, and a mechanochromic color change from yellow to dark green. The reverse color change, along with a morphological and conformational change to the folded conformer, was performed by solvent vapor exposure (chloroform). The twisted and folded conformers showed ambipolar (hole/electron) and hole-only transport properties, respectively.

    We present a systematic comparative density functional theory-density functional tight binding study of multiple derivatives of C60 and C70 with different addends, in molecular as well as solid state. In particular, effects due to fullerene size, type and number of addends, and of crystallinity on band structure, charge transport, and optical properties are investigated. These are important, in particular, for rational selection of fullerene derivatives as acceptor and electron transport layers in organic as well as planar inverted perovskite solar cells. We find that by the choice of type and number of addends, one can modulate the LUMO within 0.4 eV. Changes in the HOMO can reach 0.7 eV. Substituting C70 for C60 results in destabilization of the HOMO by about 0.1 eV for indene and quinodimethane addends and by a less significant amount for PCBM addends. The effect of C70-C60 substitution on the LUMO is of similar magnitude. A more significant change in HOMO-LUMO energy is seen for the aryl addends. On the other hand, all C70 based molecules have strong visible absorption. For most addends, the crystal packing leads to a stabilization of both the LUMO and HOMO by about similar to 0.2 and similar to 0.1 eV, respectively, vs. single molecules. When using bis-addends, it is also possible to enhance the visible absorption. Electron and hole transport rates are computed to vary vastly depending on the addends chosen; specifically, we compute that indene and quimodimethane addends can enhance charge transport rates while the aryl addend is predicted to result in substantially smaller mobilities of electrons and holes, vs. PC60BM. Furthermore, the -CH2 and bisaddend addition can significantly enhance the charge transfer rates for the PCBM addend.

    Transparent carbon electrodes, carbon nanotubes, and graphene were used as the bottom electrode in flexible inverted perovskite solar cells. Their photovoltaic performance and mechanical resilience were compared and analyzed using various techniques. Whereas a conventional inverted perovskite solar cells using indium tin oxide showed a power conversion efficiency of 17.8%, the carbon nanotube- and graphene-based cells showed efficiencies of 12.8% and 14.2%, respectively. An established MoO3 doping was used for carbon electrode-based devices. The difference in the photovoltaic performance between the carbon nanotube- and graphene-based cells was due to the difference in morphology and transmittance. Raman spectroscopy, and cyclic flexural testing revealed that the graphene-based cells were more susceptible to strain than the carbon nanotube-based cells, though the difference was marginal. Overall, despite higher performance, the transfer step for graphene has lower reproducibility. Thus, the development of better graphene transfer methods would help maximize the current capacity of graphene-based cells.

    Organic-inorganic halide perovskite solar cells have received much attention because they achieve high power conversion efficiencies while providing the advantages of thin-film solar cells, namely, solution processability and potentially low fabrication costs. However, at the current level of halide perovskite solar cell technology, these advantages cannot be maximized because of structural and material limitations. Here, we provide a solution to these problems by replacing conventional metal and metal oxide electrodes with carbon nanotube electrodes. We also simplified the structure to achieve entirely solution-processable perovskite solar cells. Through this study, we demonstrate the function of carbon nanotubes as both the anode and the cathode in perovskite solar cells. Economic modeling suggests that this novel architecture reduces costs dramatically. This work realizes innovations in the materials, costs, and processing of inverted-type perovskite solar cells.

    Bilayer graphene (BLG) comprises a 2D nanospace sandwiched by two parallel graphene sheets that can be used to intercalate molecules or ions for attaining novel functionalities. However, intercalation is mostly demonstrated with small, exfoliated graphene flakes. This study demonstrates intercalation of molybdenum chloride (MoCl5 ) into a large-area, uniform BLG sheet, which is grown by chemical vapor deposition (CVD). This study reveals that the degree of MoCl5 intercalation strongly depends on the stacking order of the graphene; twist-stacked graphene shows a much higher degree of intercalation than AB-stacked. Density functional theory calculations suggest that weak interlayer coupling in the twist-stacked graphene contributes to the effective intercalation. By selectively synthesizing twist-rich BLG films through control of the CVD conditions, low sheet resistance (83 Ω ▫(-1) ) is realized after MoCl5 intercalation, while maintaining high optical transmittance (≈95%). The low sheet resistance state is relatively stable in air for more than three months. Furthermore, the intercalated BLG film is applied to organic solar cells, realizing a high power conversion efficiency.

    C-60 o-quinodimethane bisadducts [C-60(QM)(2)] are promising electron acceptors for bulk heterojuction (BHJ) organic solar cells (OSCs). However, previous production of C-60(QM)(2) often resulted in excessive regioisomers, which were difficult to purify and might consequently obscure the structure performance study of the organofullerene acceptors. Herein, the electrosynthesis of C-60(QM)(2) is reported. The reaction exhibits a strong regiocontrol with generation of fewer regioisomers. Pure regioisomers of cis-2, trans-3, and e C-60(QM)(2) are obtained, and the structures are solved with single-crystal X-ray diffraction. Interestingly, the cis-2 and trans-3 regioisomers exhibit better photovoltaic performance than the e regioisomer in the OSCs based on poly(3-hexylthiophene) (P3HT), which can be correlated with their structural difference.

    Organic functionalization of lithium-ion-containing [60]fullerene, Li+@C-60, was performed by using diphenyl(diazo)methane as a stable, readily available diazo compound to obtain lithium-ion-containing [5,6]- and [6,6]-diphenylmethano[60]fullerenes, Li+@C61Ph2. The bis(trifluoromethanesulfonyl)imide (TFSI) salts of [5,6]- and [6,6]-Li+@C61Ph2 were successfully separated by using a cation exchange column with eluent containing LiTFSI. Improved separation protocol and high crystallinity of ionic components in less polar solvents enabled separate crystallization of each isomer. Both [5,6]-open and [6,6]-closed structures of Li+@C61Ph2 were determined by synchrotron radiation X-ray crystallography. Elucidating the [5,6] -open methano[60]fullerene (fulleroid) structure will contribute to materials research on fulleroids.

    In this work, both anode and cathode interfaces of p-i-n CH3NH3PbI3 perovskite solar cells (PVSCs) are simultaneously modified to achieve large open-circuit voltage (V-oc) and fill factor (FF) for high performance semitransparent PVSCs (ST-PVSCs). At the anode, modified NiO serves as an efficient hole transport layer with appropriate surface property to promote the formation of smooth perovskite film with high coverage. At the cathode, a fullerene bisadduct, C-60(CH2)(Ind), with a shallow lowest unoccupied molecular orbital level, is introduced to replace the commonly used phenyl-C-61-butyric acid methyl ester (PCBM) as an alternative electron transport layer in PVSCs for better energy level matching with the conduction band of the perovskite layer. Therefore, the V-oc, FF and power conversion efficiency (PCE) of the PVSCs increase from 1.05 V, 0.74 and 16.2% to 1.13 V, 0.80 and 18.1% when the PCBM is replaced by C-60(CH2)(Ind). With the advantages of high V-oc and FF, ST-PVSCs are also fabricated using an ultrathin transparent Ag as cathode, showing an encouraging PCEs of 12.6% with corresponding average visible transmittance (AVT) over 20%. These are the highest PCEs reported for ST-PVSCs with similar AVTs paving the way for using ST-PVSCs as power generating windows.

    We demonstrated single-walled carbon nanotubes (SWNTs) electrode-based small molecule organic solar cells (OSCs) using diketopyrrolopyrrole donor, DPP(TBFu)2 as an electron donor with [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) as an electron acceptor. SWNT films with 60% transmittance (at 550 nm) were dry-transferred onto glass substrates to replace conventional indium tin oxide (ITO) electrodes. In order to improve the conductivity of the SWNT electrodes, MoOx thermal doping was applied followed by spin coating of poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) to enhance doping and electrode blocking function. The indium-free devices showed a power conversion efficiency (PCE) of 1.00% while ITO-based devices showed a PCE of 3.79%.

    A regioselective and highly efficient electrochemical method for direct acylation and carboxylation of a [60] fulleroindoline has been developed. By using inexpensive and readily available acyl chlorides and chloroformates, both keto and ester groups can be easily attached onto the fullerene skeleton to afford 1,2,3,16-functionalized [60] fullerene derivatives regioselectively. In addition, a plausible mechanism for the formation of fullerenyl ketones and esters is proposed, and their further transformations under basic and acidic conditions have been investigated.

    One of the primary challenges for high-quality metal chalcogenide film growth by a chemical solution approach is to avoid the use of volatile/hazardous organic solvents during the fabrication processes. Herein, we demonstrate an organic solvent-free solution processing method which has the ability to enable growth of a diverse range of metal chalcogenide films. The processing solution is prepared by combining the required metal ions with non-volatile and non-flammable ionic liquid precursor solutions. These stable and homogeneous solutions can form a variety of high-quality and uniform metal chalcogenide films. Due to the facile and instant control of the stoichiometry used in this method, the band gap of multi-element compound semiconductors, for example quinary Cu2ZnSn( S, Se) (4), can be easily tuned from 1.01 eV of Cu2ZnSnSe4 to 1.52 eV of Cu2ZnSnS4. The resulting film also shows high hole mobility with a maximum of 56.9 cm(2) V-1 s(-1) for a carrier concentration of 3.24 x 10(16) cm(-3) at room temperature. Cu2ZnSnS4-based solar cells displayed an efficiency of 5.68%, which is comparable to the reported efficiencies of solar cells prepared by methods involving organic solvents ( 5.0-6.4%).

    Single-bonded fullerene dimers, (C60R)(2) (R = (2-methoxyphenyl)dimethylsilylmethyl, (isopropoxy) dimethylsilylmethyl, and 2-methoxy-5-methylphenyl), afforded fullerene derivative cations (RC60+) in the presence of an oxidant (I-2, CuCl2, or CuBr2), leading to 5- and 7-membered cyclo[60]fullerene derivatives such as cyclo[60]fullerenes containing a Si-O bond, cyclo[60]fullerenes containing a C-60-O bond, and dihydrobenzofurano[60]fullerene. The reaction mechanism involved thermal homolytic cleavage to give fullerene radicals, oxidation of the radicals to generate fullerene cations, and then demethylative cyclization in which the fullerene cationic centers interact with an aromatic group or the oxygen atoms of methoxy groups to produce the cyclized products. The obtained cyclo[60]fullerene derivatives were used in bulk-heterojunction organic solar cells and showed moderate power conversion efficiency and respectable open-circuit voltage.

    We synthesized Fluorenylidene-acridanes that changes their absorption colors by mechanical stimuli. We elucidated that the mechanism of this appearance change is based on conformational change of the molecules, which can be controlled by morphological change in the solid. We also achieved X-ray single crystal structures determination of both folded and twisted conformers. This revealed that absorption color change was governed by switching charge transfer absorption.

    We synthesized magnesium porphyrin derivatives as electron donors used for small-molecule solution-processable organic thin-film solar cells. Especially, we synthesize these derivatives by using two or four diketopyrrolopyrroles (DPPs) organic dyes connected to the porphyrin cores through triple bonds. In bulk heterojunction organic thin-film solar cells using these porphyrins as electron donors and fullerene derivatives as electron acceptors, we achieved 7.40% power conversion efficiency. We also revealed that magnesium porphyrins have higher solubility and longer excitation lifetime than zinc congeners.

    高精度な構造制御および高機能化した単層カーボンナノチューブ(SWNT)やグラフェンを用いた太陽電池の開発を進めた.
    SWNTの構造(カイラリティ)の制御合成技術確立を目指し,水晶基板上に合成した水平配向SWNTに対しラマン散乱マッピング計測を行うことで,個々のSWNTのカイラリティを分析した.ラマン散乱マッピングと電子顕微鏡(SEM)観察を相互的に行うことで,カイラリティとSWNT成長長さとの関係などを明らかにすることで,SWNT成長におけるカイラリティ依存性を示すことに成功した.
    また,グラフェンについては,高品質で大面積なもののCVD合成法の確立が求められている.ここでは,SWNTの合成法として非常に有効であるアルコールを炭素源ガス分子として用いたアルコールCVD法を応用し,グラフェン合成技術開発を行った.基板として銅箔を使用し,約1000℃での合成においてエタノール圧力や流速を制御することで,ミリメートルオーダーの非常に大きなグラフェン合成に成功した.
    さらに,最近注目を集めている太陽電池の1つであるペロブスカイト型太陽電池へのSWNT応用を試みた.SWNT薄膜は高い光透過性を有すると同時に電気伝導性も高く,優れた透明導電膜である.これを利用し,ペロブスカイト型太陽電池の電極材料としてSWNT薄膜を用い,高い変換効率を得ることに成功した.また,SWNT薄膜に化学的ドーピングや金属酸化物微粒子を蒸着することで,その電気伝導特性を制御することができた.これら機能化したSWNT薄膜は,ペロブスカイト型太陽電池において正孔輸送層(または電子ブロッキング層)として機能しており,これにより太陽電池として高い変換効率を得ることが出来たと言える.

    本研究では,フラーレン-遷移金属錯体の合成手法の深化と新反応の発見を可能とする新規高選択的触媒反応場を構築することを目的として,これまで知られている配位子では行えなかった新しい立体的効果,電子的効果を与えることができるフラーレン-遷移金属錯体の合成を行っている.新しい立体効果をもたらすために,シクロペンタジエニル基周辺に深いカップ状のキャビティーを構築した.すなわち,丸いフラーレンの1つの5員環周辺に集中して位置選択的および高効率に剛直な壁およびコネクションを有する有機基(CH2SiMe2Ar ; Arはビフェニル基,テルフェニル基等)を導入した.ここにおいて,フラーレンの1つの5員環がカップの底部,ケイ素原子が底と壁をつなぐコネクション,Ar基が壁となっている.このカップの底にルテニウムやパラジウムなどの金属原子を配位させ,錯体を合成することに成功した.
    また,新しい電子的効果をもたらすフラーレン配位子を創製するために,五重付加型フラーレン(C60R5)の還元に関する研究を行った.C60R5のモノアニオン,ジアニオン,トリアニオンを単離し,特に,モノアニオン,ジアニオンについてはX線により結晶構造を明らかにした.ジアニオンは開殻構造を有するラジカルジアニオンであり,結晶中ではラジカルカップリングしたダイマーを与えた.トリアニオンについては七重付加型フラーレン,八重付加型フラーレンの優れた出発物質であることを明らかにした.また,フラーレン-遷移金属錯体の還元も行い,モノアニオン,ジアニオンを単離した.
