| Abstract(in English) | Properties of organic thin photovoltaic (PV) Cells using fullerene C_<60> as acceptor with different purities were studied. Short-circuit current, open-circuit voltage and fill factor of PV cells increase as C_<60> material purity increases. The conductivity of low-purity C_<60> thin film is lower than that of high-purity one. The lower conductivity of low-purity C_<60> layer is one of the causes of decrease in cell performance. The current with exciting copper phthalocyanine, which is used as donor, only and C_<60> only are measured and we find that the generation and/or the diffusion of excitons are prevented by impurities in C_<60> layer. We estimate the absorption at each positions in cell and examine the effect of the impurities for the generation and/or the diffusion excitons. |
