We report here on the latest progress in the use of halide perovskites in solar cells and photocatalysis. This family of compounds has expanded in terms of chemical composition, crystal structure types and optoelectronic properties. The power conversion efficiency of the perovskite solar cells currently exceeds values of 25%. However, the interest has largely shifted towards improving the stability of the materials under ambient conditions. At the same time, the photocatalytic efficiency of the halide perovskites is also investigated, revealing new applications such as CO₂ reduction, H₂ evolution and organic synthesis and pollutants photodecomposition. The best materials, such as doped-CH(NH₂)2PbI₃ and CsPbBr₃), and engineering methods for both solar cells and photocatalysis have led to devices closer to commercial use than ever before.

我们在此报告卤化物钙钛矿在太阳能电池和光催化中的最新进展。这一系列化合物在化学成分、晶体结构类型和光电特性方面有所扩展。钙钛矿太阳能电池的功率转换效率目前超过 25%。然而，人们的兴趣在很大程度上转向了提高材料在环境条件下的稳定性。同时，还研究了卤化物钙钛矿的光催化效率，揭示了 CO ₂还原、H ₂析出和有机合成和污染物光分解等新应用。最好的材料，例如掺杂的 CH(NH ₂ )2PbI ₃和 CsPbBr ₃），太阳能电池和光催化的工程方法使设备比以往任何时候都更接近商业用途。
