Investigations of the photogeneration process and photovoltaic effect in recently synthesized polysilane and its mixtures with fullerene (C60) are reported. Dependencies of the photogeneration quantum yield on the wavelength of the exciting radiation and on electric field were determined by the surface potential decay technique. It was found that addition of C60 improves the photogeneration efficiency. The Onsager model was used to analyse the obtained results. To check potential application properties of the investigated material, the photovoltaic effect was investigated in devices with an active layer made of mixtures of polysilane and C60. It was found that the power conversion efficiency of the device is dependent on the C60 concentration, the photovoltaic effect was observed, however, even if the amount of C60 was low (5 wt. %).
