The interface electron states between CGL and CTL in sample A efficiently accelerated photogeneration carrier transport processes to bring about a lower V-r value and higher light sensitivity than sample B. The process might be interpreted as a kind of assistance sensitization effect based on interfacial electron states in the high fields; that is to say, the interface electron states between CGL and CTL accelerated carriers injection from CGL into the gap states of CTL, and followed by the interface electron states modulated transport processes of carriers in the CTL.展开更多

It is found that N, N′ dimethyl perylene 3,4:9, 10 bis (dicarboximide) and perylene 3,4:9,10 tetracarboxylic acid bisbenzimidazole show excellent photoconductivities, their charge acceptance reaches 700 V and 485 V, and the photosensitivity is 45 lx·s and 10 lx·s with dark decays 70 and 60 V/s respectively. The introduction of chlorine atoms can improve their photoelectric properties. SEM analyses also show that the dispersion of pigment in OPC could affect its photosensitivity.展开更多
