英文摘要： The project is planned to study the bulk heterojunction solar cell of inorganic compound conductor nano-materials. First, the Ti thin film will be prepared on the substrate of the transparent conductive glass (FTO) by magnetron sputtering. Followed, one-dimensional TiO2 nanotube array will be grown on FTO substrate via anodic oxidation, and then the TiO2 nanotubes will be treated by II-VI narrow band gap composite quantum dot (CdS and CdSe). The purpose is broader spectrum application range, enhance charges separation efficiency and inhibit the recombination of electron-hole pairs. Finally, the effective TiO2 nanotube arrays solar cell will be prepared. The related work will reveal the the relationship between quantum dot sensitizers, array structure and the overall performance of the solar cells, achieve function complements and advantages collaborative between inorganic semiconductor materials. Then, it will be elucidating the photoelectric conversion mechanism about the charge absorption, separation, transport. It is expected to realize the efficient absorption of visible light, obtain the novel TiO2 nanotube arrays solar cells with high photoelectric conversion efficiency. This study will provide scientific data and the theoretical guidance for its potential application.
