Fullerene (C60) film is one of possible candidates for high-performance thermoelectric materials because of its giant Seebeck coefficient (S) of -110 mV/K at room temperature (RT) [1]. For application of the C60 film to practical thermoelectric devices, it is indispensable to improve a very low electrical conductivity (σ = ca.10-5 Ω-1cm-1) of the C60 film. In addition, since the C60 film exhibits a large N-type S value (< 0), a large P-type S value (> 0) should be emerged for C60-based films, because practical thermoelectric devices have a -type structure composed of a sequential array of P- and N-type thermoelectric materials. In this study, we have demonstrated that the P-type thermoelectric C60-based films can be formed by co-deposition of C60 and molybdenum oxide (MoO3).

Organic photovoltaic cells (OPVs) have been extensively investigated owing to their fascinating advantages such as flexibility, highly designability, and low fabrication cost. However, the energy conversion efficiency (η) of OPVs is still ca. 10%, which is much lower than those (ca. 25% at most) of the conventional Si solar cells. In order to improve the η of OPVs, it is indispensable to increase both the short-circuit current and open-circuit voltage simultaneously. In the former case, it is important to understand the elementary processes of photoelectric conversion [1-4]. In the present study, we examined the structural and optical properties of lead phthalocyanine (PbPc) used as a donor for C60-based OPVs, because PbPc films exhibit absorption bands in a wide wavelength region of 400-1000 nm.

Fullerene (C60) film exhibits a giant Seebeck coefficient (S) of -110 mV/K at room temperature (RT) [1], thus being one of candidates for novel flexible thermoelectric materials. Our goal is to fabricate high-performance thermoelectric conversion devices with a π-type structure composed of a sequential array of P- and N-type C60-based films. We recently found that the composite film formed by co-deposition of C60 and molybdenum oxide (MoO3) shows a giant P-type S of +40 mV/K and an electrical conductivity (σ) greater by 102 times than that of pristine C60 films [2]. Although the pristine C60 film has the giant N-type S as described above, it shows a very low σ of ca. 10-6 Ω-1cm-1. In this study, we aim to form a highly conductive N-type C60-based film by co-deposition of C60 and cesium carbonate (Cs2CO3).
