Abstract: The excellent photoelectric properties of perovskite materials make perovskite solar cells one of the fastest growing photovoltaic technologies. Recent studies have found that single crystal perovskite films without grain boundaries have lower defect density, higher carrier mobility, longer carrier recombination life, higher stability and wider range of light absorption. Therefore, it is expected to prepare more efficient and stable perovskite solar cells. This article briefly introduces the basic structure and development history of single crystal perovskite solar cells, and focuses on the preparation methods of single crystal perovskite films and bulk single crystal perovskites. Beside, the efficiency of single crystal perovskite solar cells prepared by different methods are compared. Finally, the current problems and future development of single crystal perovskite solar cells are briefly analyzed and prospected.

Key words: single crystal perovskite, perovskite solar cell, single crystal perovskite film, bulk single crystal perovskite, preparation method
