【Abstract】 The photovoltaic features and photo-induced interfacial charge transfer of CuPc-modified Q-CdS films were investigated by surface photovoltage spectra and optical absorption spectra. The results show that the interfacial chaxge transfer and photosensitization between cuPc and Q-cds occur under inuAnnation. Based on the observations,the generation and processes of the charge transfer are proposed and discussed.更多还原
