The photovoltaic properties of dimeric porphyrin have been studied by means of surface photovoltage spectrum(SPS) and field induced surface photovoltage spectrum(FISPS). The results show that a negative SPV response b...
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 interfac...
