摘要

以TiCl3为钛源,水热法制备高散射性能的锐钛矿TiO2空心微球。以商业TiO2(P25)/NaYF4∶Yb3+,Er3+混合材料为底层薄膜,TiO2空心微球为反射层组成双层结构光阳极薄膜,优化了太阳能电池性能。结果表明:新型结构的太阳能电池短路光电流(Jsc=16.81mA/cm2)、开路光电压(Voc=0.78V)、填充因子(FF=0.66)和光电转化效率(η=8.65%),其光电转化效率与纯P25(6.70%)光阳极和P25/NaYF4∶Yb3+,Er3+(7.35%)光阳极相比较分别提升了29%和18%。

Abstract

Hollow TiO2 microspheres were synthesized from TiCl3 by a simple hydrothermal method.In order to improve the performance of DSSC,double-layerd photoanode was fabricated by using P25/NaYF4∶Yb3+,Er3+ as substrate layer and hollow TiO2 microshperes as the reflecting layer.The results shown that the double-layer TiO2 photoanode exhibited an open-circuit photovoltage (Voc) of 0.78,a short-circuit photovoltage(Jsc) of 16.81mA/cm2,a fill factor (FF) of 0.66,which lead to an overall energy-conversion efficiency (η) of 8.65%.Compared with the electrodes made of P25(6.70%) and P25/NaYF4∶Yb3+,Er3+(7.35%),a increase of 29% and 18% energy-conversion efficiency was observed respectively.
