Abstract

This paper reports the development of morphology-tuned TiO2/ZnO films and their application to the electrode in dye-sensitized solar cells. Amorphous TiO2 precursor films with different morphologies can be synthesized under different processing conditions by our previously developed peroxotitanate-complex deposition process, which employs a supersaturated peroxotitanate aqueous solution. The ZnO nanowire aligns were grown by a two-step method, in which well oriented arrays of ZnO nanowires were prepared on a pre-prepared ZnO seed layer. The cell performance using the prepared TiO2/ZnO films shows the possibility to integrate these films into solar cells. However, the crystallization and morphology should be further optimized to improve the conversion efficiency to be a competitive level.
