As a rising star of third-generation photovoltaic technology, organic–inorganic halide perovskite solar cells (PSCs) have exhibited high power conversion efficiency. However, the most investigated high-performance perovskites contain toxic lead, which may hinder their widespread applications. Among various alternative metal ions to replace lead for environmentally benign perovskites, tin has been successfully used in PSCs with the highest efficiency over 13% at present, making tin-based perovskites the most promising active materials for lead-free PSCs. In this review, we first summarize the device design of PSCs and the physical properties of tin-based perovskites. Then we state the major challenges for this field and discuss the essential techniques in film preparation. Specifically, tin rich conditions (tin halide) and suitable reducing agents are needed in the film preparation to prohibit Sn²⁺ oxidation, and solvent modulation is a feasible approach for controlling the film morphology. Meanwhile, chemical substitutions of A site and B site cations and X site anions to improve the optoelectronic properties of tin-based perovskites are comprehensively addressed. Moreover, tin–lead mixed perovskites that contain less lead than conventional perovskites for high-performance PSCs and tandem solar cells are discussed. This comprehensive review can shed light on the development of environmentally friendly PSCs and provide a guideline for realizing lead-free PSCs with high efficiency and stability via synergistic approaches.

锡基钙钛矿太阳能电池的最新进展

作为第三代光伏技术的后起之秀，有机-无机卤化物钙钛矿太阳能电池（PSC）表现出高功率转换效率。但是，研究最多的高性能钙钛矿包含有毒的铅，这可能会阻碍其广泛的应用。在各种替代环境友好的钙钛矿中替代铅的金属离子中，锡已成功用于PSC中，目前效率最高超过13％，使锡基钙钛矿成为无铅PSC最具前景的活性材料。在这篇综述中，我们首先总结了PSC的器件设计以及锡基钙钛矿的物理特性。然后，我们陈述了该领域的主要挑战，并讨论了胶片制备中的基本技术。具体来说，²⁺氧化和溶剂调节是控制薄膜形态的可行方法。同时，全面讨论了A位和B位阳离子和X位阴离子的化学取代以改善锡基钙钛矿的光电性能。此外，还讨论了用于高性能PSC和串联太阳能电池的铅-钙混合钙钛矿，其铅含量低于传统钙钛矿。这份全面的综述可以阐明环保型PSC的发展，并为通过协同方法实现高效，稳定的无铅PSC提供指导。
