The advent of organic-inorganic hybrid metal halide perovskites has revolutionized photovoltaics, with polycrystalline thin films reaching over 26% efficiency and single-crystal perovskite solar cells (IC-PSCs) demonstrating ≈24%. However, research on single-crystal perovskites remains limited, leaving a crucial gap in optimizing solar energy conversion. Unlike polycrystalline films, which suffer from high defect densities and instability, single-crystal perovskites offer minimal defects, extended carrier lifetimes, and longer diffusion lengths, making them ideal for high-performance optoelectronics and essential for understanding perovskite material behavior. This review explores the advancements and potential of IC-PSCs, focusing on their superior efficiency, stability, and role in overcoming the limitations of polycrystalline counterparts. It covers device architecture, material composition, preparation methodologies, and recent breakthroughs, emphasizing the importance of further research to propel IC-PSCs toward commercial viability and future dominance in photovoltaic technology.
有机-无机杂化金属卤化物钙钛矿的出现彻底改变了光伏领域，多晶薄膜的效率超过了26%，单晶钙钛矿太阳能电池（IC-PSC）的效率约为24%。然而，对单晶钙钛矿的研究仍然有限，在优化太阳能转换方面存在关键差距。与具有高缺陷密度和不稳定性的多晶薄膜不同，单晶钙钛矿的缺陷极少，载流子寿命延长，扩散长度更长，这使其成为高性能光电器件的理想选择，也是理解钙钛矿材料行为的关键。本综述探讨了IC-PSC的进展和潜力，重点关注其卓越的效率、稳定性以及在克服多晶同类产品局限性方面的作用。它涵盖了器件结构、材料组成、制备方法和近期突破，强调了进一步研究对于推动IC-PSC实现商业可行性并在光伏技术中占据未来主导地位的重要性。
