Although antimony sulfoiodide (SbSI) exhibits very interesting properties including high photoconductivity, ferroelectricity, and piezoelectricity, it is not applied to solar cells. Meanwhile, SbSI is predominantly prepared as a powder using a high‐temperature, high‐pressure system. Herein, the fabrication of solar cells utilizing SbSI as light harvesters is reported for the first time to the best of knowledge. SbSI is prepared by solution processing, followed by annealing under mild temperature conditions by a reaction between antimony trisulfide, which is deposited by chemical bath deposition on a mesoporous TiO₂ electrode and antimony triiodide, under air at a low temperature (90 °C) without any external pressure. The solar cells fabricated using SbSI exhibit a power conversion efficiency of 3.05% under standard illumination conditions of 100 mW cm⁻².

基于光捕获二氧化硫锑的高效太阳能电池

尽管硫化亚锑（SbSI）表现出非常令人感兴趣的特性，包括高光电导性，铁电性和压电性，但它并未应用于太阳能电池。同时，主要使用高温高压系统将SbSI制成粉末。在本文中，首次报道了利用SbSI作为光收集器的太阳能电池的制造。SbSI的制备方法是固溶处理，然后在温和的温度条件下通过三硫化锑之间的反应进行退火，该三硫化锑通过化学浴沉积法沉积在介孔TiO _2上电极和三碘化锑，在低温（90°C）的空气中，没有任何外部压力。使用SbSI制造的太阳能电池在100mW cm ^-2的标准照明条件下表现出3.05％的功率转换效率。
