| 英文摘要 | Photogenerated charge carriers transfer and transport kinetics of nanocrystalline semiconductor thin film electrodes were studied by Intensity Modulated Photocurrent Spectroscopy (IMPS). Measuring the applied potential and sodium polysulfide solution concentration dependence of IMPS response of nanocrystalline CdSe electrodes, the interfacial holes transfer including direct process and indirect process via surface states were analyzed in terms of the parameters: normalized steady state photocurrents and surface states lifetimes. The transport processes of electrons were examined by determining the electron diffusion coefficient of nanocrystalline TiO2 electrodes obtained at different intensities of background light. HCl chemical treatment led to the increase of electron transport coefficient effectively indicating the improvement of electrons transport behavior in the nanocrystalline TiO2 electrodes. |
