摘要
CH_3NH_3PbI_3 sensitizers are prepared with different mixed solvents. Using butyrrolactone/dimethyl sulphoxide mixed solvent, a smooth film with roughness of 12 nm is obtained. The prepared films are used as photocathode photosensitizers of p-DSSC. Current-voltage(I-V) curve indicates that CH_3NH_3PbI_3 with butyrrolactone/dimethyl sulphoxide presents a higher J_(sc) of 7.5 m A cm~(-2) and a higher efficiency of 0.53%, which may contribute to its improved UV-vis absorption and smooth film. Electrochemical impendence spectroscopy(EIS), intensity-modulated photocurrent spectroscopy(IMPS), and intensity-modulated voltage spectroscopy(IMVS) demonstrate that CH_3NH_3PbI_3 with butyrrolactone/dimethyl sulphoxide provides improved hole collection efficiency with suppressed recombination.
