摘　　要：为了抑制、减小暗电流的生成,并且提高电子的注入效率以及传输的速率,提高太阳能电池的光电转换效率以及转换稳定性。基于SEM图像以及XPS技术对水热法制备得到TiO_2浆料的外形及其主要成分进行表征分析,结果显示出对TiO_2浆料进行La_2O_3覆膜可以对电极间的电子反应进行十分有效地控制,使得太阳能电池的光电化学性能得到较大幅度的提升。In order to Restrain and reduce generation of dark current,improve electron injection efficiency and the rate of transmission,the photoelectric conversion efficiency and its stability of solar cells are enhanced.The morphology and the main components of the reparation of TiO 2 slurry based on Hydrothermal Method were characterized by Scanning electron microscopy(SEM)and X ray photoelectron spectroscopy(XPS).The results shows that the La 2O 3 coating layer can inhibit the electron recombination at the interface and improve the photoelectric chemical properties of cells under the same bias voltage.
