摘　　要：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 band(P) appears in the long wave region which takes on n type character and the π π * transition band takes on p type character. P band disappears under high vacuum and appears under O 2 atmosphere. The photo charge transfer process generated between π π * transition band of dimeric porphyrin and P band, which has been attributed to the photo adsorption and photo desorption of O 2 on the surface of dimeric porphyrin.The photovoltaic properties of dimeric porphyrin have been studied by means of surface photovoltage spectrum(SPS) and field induced surface photovoltage spectrum(FISPS).
