TiO2 and CdSe nanorods were prepared by a hydrothermal method. The photoelectrochemical properties of TiO2/CdSe composite film and TiO2/CdSe/PMeT film were investigated. The experiment results showed that the incident photon to current conversion efficiency (IPCE) of TiO2/CdSe/PMeT was obviously increased in comparison to that of TiO2/CdSe composite film. The experiment results showed that the p-n heterojunction existed in the TiO2/CdSe/PMeT nanostructure film, which favored the separation of electron-hole pairs generated by photoexcitation. The IPCE value of TiO2/CdSe/PMeT film was 56% at －0.2 V, and the incident light wavelength of 370 nm. The hybrid solar cell was fabricated with TiO2/CdSe nanostructure composite film and poly(3-methylthiophene) (PMeT). The conversion efficiency of the hybrid solar cell was 0.08%, short current 0.61 mA/cm2, open voltage 0.4 V, fill factor 0.33, under irradiation of 100 mW/cm2 white light from a Xe lamp.
