报道了一种新型的BiOI/介孔TiO 2太阳能电池光阳极，该阳极是通过化学浴沉积法（CBD）将BiOI附着在三维介孔TiO 2薄膜上制备的。BiOI是一种高效、环境友好的半导体敏化剂，可使TiO 2对可见光产生响应。基于该光阳极，BiOI敏化的介孔TiO 2基太阳能电池表现出良好的光伏性能。同时，通过改变沉积浸渍的周期，也实现了光伏性能的优化。电池的最高开路电压和短路电流分别可达0.5V和1.5mA/cm（2）。
We reported a novel BiOI/mesoporous TiO2 photoanode for solar cells, which was fabricated with BiOI attached onto a three-dimensional mesoporous TiO2 film by a chemical bath deposition (CBD) method. BiOI was revealed as an efficient and environmental friendly semiconductor sensitizer to make TiO2 respond to visible light. Based on this photoanode, mesoporous TiO2-based solar cell sensitized by BiOI exhibited promising photovoltaic performance. Meanwhile, the optimization of photovoltaic performance was also achieved by varying cycles of deposition immersions. The highest open circuit voltage and short circuit current of the solar cell can reach 0.5 V and 1.5 mA/cm(2), respectively.
