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.
我们报道了一种用于太阳能电池的新型BiOI/介孔TiO₂光阳极，它是通过化学浴沉积（CBD）方法将BiOI附着在三维介孔TiO₂薄膜上制备而成。BiOI被证明是一种高效且环保的半导体敏化剂，可使TiO₂对可见光产生响应。基于这种光阳极，由BiOI敏化的介孔TiO₂基太阳能电池表现出了良好的光伏性能。同时，通过改变沉积浸泡的循环次数也实现了光伏性能的优化。该太阳能电池的最高开路电压和短路电流分别可达0.5 V和1.5 mA/cm²。
