Photoactive Oxide Films and Heterostructures Preparation

Abstract

The nanotechnology and molecular design should be used for the Dye Solar Cells (DSC) preparation. In this paper, we present the extraction-pyrolysis technique for the photoactive oxide TiO2, Ti2ZnO4 and conductive oxide InSnO films sensible by Ru-extract on glass substrate preparation. It is a low cost and large-scale technique for nanosize oxide films obtaining. The attempts to use the photoactive oxides TiZnO for the protection and enhancement of the Si photovoltaic cells were made. The properties of heterostructures shown that the thin oxide film on the porous Si improve the photovoltaic performance and long time stability of solar cells.
