Abstract: In the past decade or so, thanks to the excellent photovoltaic properties of organic-inorganic hybrid perovskite materials, the certified efficiency of perovskite solar cells has increased to 26.7%, which is the most rapidly developing technology in photovoltaics. With a less trap-state density, superior photovoltaic properties and better stability than the widely studied polycrystalline thin films, single-crystal perovskite without grain boundaries shows a greater potential for the preparation of higher efficiency and longer lifetime photovoltaic devices. In addition, single-crystal perovskite solar cells are excellent models for further mechanism studies related to the surface and grain boundaries of perovskite materials. Unfortunately, limited by the high difficulty of growing 3D single-crystal thin films, only a few groups have carried out the development of single-crystal perovskite solar cells, resulting in the development of this field lagging far behind that of polycrystalline film counterparts. Therefore, this review introduces the methods of single-crystal perovskite thin films growth and summarizes the recent research progress in perovskite single-crystal solar cells. Finally, the challenges and development prospects of single-crystal perovskite solar cells are discussed in detail.
