摘要	Tin perovskite solar cell received great attention in recent years owing to its optimum bandgap and heavy metal-free property. The main concern for the development of tin perovskite is the oxidation from Sn2+ to Sn4+. Herein, we report a surface hetero-protection strategy to avoid the surface reaction of tin perovskite. Three types of materials, including low-dimensional tin perovskite, alkali metal halide, and oxides of group IVA element, are exploited as protecting materials on tin perovskite surface with first-principles calculation. The lattice mismatch, oxidation resistance, and interface stability of these materials are investigated to search for ideal protecting-layer materials. After screening over 30 candidates, we finally obtain 8 suitable materials (SiO2, GeO2, KCl, NaBr, CsF, LiF, LiI, CsSn2Br5) for hetero-protection of tin perovskite. To further understand their application potential in a solar cell device, we then calculate the property of charge transfer between the interface of these materials and tin perovskite. Our study provides a guide for the experimental realization of efficient and stable tin perovskite solar cell.
