摘要
以水热法为基础,向其溶胶中掺入适量的P25(二氧化钛粉体),来制备纳晶TiO_2胶体,以纳晶TiO_2为电子传输体组装染料敏化太阳能电池.通过XRD、SEM、UV-vis和电池的光电性能测试,来分析掺入P25对染料敏化太阳能电池性能的影响.结果表明,加入适量P25([P25]/[Ti]=0.2)后,染料敏化太阳能电池性能达到最佳值,在100 mW/cm^2光照条件下,光电转换效率达到5.4%.
Nano-crystalline titanium dioxide (TiO2) colloid was prepared from mixing TiO2 nano- crystalline P25 to sol by hydrothermal method. Using the nano-crystaUine TiO2 as the electron transmission medium, a dye-sensitized solar cell (DSSC) was assembled. The influence of amount of mixing P25 on the photoelectronic properties of the DSSC yeas confirmed by XRD pattern, SEM observation, UV-vis spectra, and I-V curve of the solar cells. The results show that when mixing proper P25 ( [P25]/[Ti] = 0.2) to sol, the photoelectric performance of the DSSC is the best. The photoelectric conversion efficiency with the film electrode could be 5.4 % irradiated by a solar simulator with 100 mW/cm^2.
