Digital Simulation of Photovoltage Transient Behaviors of CdSe Thin Film Electrode

Photovoltage transient behaviors of CdSe thin films electrode have been measured by plused laser irradiation. Both fast and slow transients based on photogeneration, recombination and interfacial charge transfer were observed in polysulfide and ferro-ferricyanide solution. A digital simulation technique were applied for theoretical analysis. From the simulated parameters of interfacial redox reaction rate constant K_p and K_n , the Kinentic bahaviours of interfacial charge transfer of CdSe thin film electrode in different solution were discussed.
