Hybrid organic-inorganic halide perovskites (HOIHPs) have recently emerged as a flourishing area of research. Their easy and low-cost production and their unique optoelectronic properties make them promising materials for many applications. In particular, HOIHPs hold great potential for next-generation solar cells. However, their practical implementation is still hindered by their poor stability in air and moisture, which is responsible for their short lifetime. Optimizing the chemical composition of materials and exploiting non-covalent interactions for interfacial and defects engineering, as well as defect passivation, are efficient routes towards enhancing the overall efficiency and stability of perovskite solar cells (PSCs). Due to the rich halogen chemistry of HOIHPs, exploiting halogen bonding, in particular, may pave the way towards the development of highly stable PSCs. Improved crystallization and stability, reduction of the surface trap states, and the possibility of forming ordered structures have already been preliminarily demonstrated.
有机-无机卤化物杂化钙钛矿（HOIHPs）最近已成为一个蓬勃发展的研究领域。它们易于生产且成本低廉，以及独特的光电特性使其成为许多应用的有前景的材料。特别是，HOIHPs在下一代太阳能电池方面具有巨大潜力。然而，它们在空气和湿气中的稳定性较差，这导致其寿命较短，从而阻碍了它们的实际应用。优化材料的化学成分，并利用非共价相互作用进行界面和缺陷工程以及缺陷钝化，是提高钙钛矿太阳能电池（PSC）整体效率和稳定性的有效途径。由于HOIHPs丰富的卤素化学性质，特别是利用卤键，可能为开发高度稳定的PSC铺平道路。已经初步证明了其结晶和稳定性的改善、表面陷阱态的减少以及形成有序结构的可能性。
