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 charge transfer and photosensitization between CuPc and Q-CdS occur under illumination. Based on the observations, the generation and processes of the charge transfer are proposed and discussed.
