英文摘要： Now, solar energy was a new type of clean and renewable energy. In order to absorb and utilize sunlight effectively, quantum dots and rare earth ions combine in this project, and the principle and character of quantum dots and rare earth ions co- sensitized TiO2 solar cell were investigated. The project will study on the effects of anodization parameters of electro chemical anodic oxidation on the TiO2 nanotube morphology and length. And study on the structure and photovoltaic behavior of quantum dots sensitized solar cells, which using CdTe, Cd1-xZnxTe to sensitize TiO2 nanotube arrays layer. And also study on the co- sensitized process on quantum dots sensitized TiO2 nanotube arrays, which using the Eu3+, Sm3+, Er 3+ and Yb3+-doped rare earth oxides as co-sensitizer. According to quantum dots and rare earth ions doped oxides materials in the visible and near infrared absorption characteristics, design and optimize the structure of TiO2 nanotube solar cells. And control of the absorption spectra to improve the photovoltaic behavior of the quantum dots and rare earth ions co- sensitized TiO2 nanotube solar cell. The investigated on these key scientific issues is great significance not only for the quantum dots and rare earth ions co- sensitized TiO2 nanotube solar cell structure and performance optimization, but
