As a new low-cost and high-efficiency photovoltaic material, perovskite solar cells have attracted much attention in recent years. Lead based perovskite solar cells have the advantages of high photoelectric conversion efficiency, low cost and easy preparation. However, their further commercialization and application are greatly limited due to the toxicity issue of lead and environmental pollution caused by lead. Therefore, some novel non-toxic or low-toxic perovskite materials have been explored for development of environmentally friendly low lead/lead-free perovskite solar cells. ⅣA group elements Ge, ⅡA group elements Mg, Ca, Sr and Ba, ⅤA group elements Bi and Sb, ⅢA group element In and transition metal element Cu are used to replace or partially replace Pb. This article briefly introduces the structure and formation conditions of hybrid perovskite materials, and focuses on the development of Sn based perovskite solar cells. The performance regulation of low lead or lead-free perovskite materials by adjusting the composition and ratio of halogen X and positive ion A are summarized. And the research progress of low lead/lead-free perovskite solar cell devices is reviewed. In addition, their future development direction is prospected.
