This paper discusses the possibility of using nanocrystalline ZnO films as photo-electrode in dye-sensitized solar cells (DSCs). The performances and mechanism of DSCs based on ZnO nanoporous film are observed by using IR, UV-vis spectra and LSV method, and compared with dye-sensitized solar cells based on nanocrystalline TiO2 films' It is found that the low efficiency of DSCs based on ZnO is due to the poor binding force between the surface of nanocrystalline ZnO films and the RuL2 (NCS)(2) ( L = 2,2'-bipydyl-4,4'-dicarboxylate) dye.
