The tremendous interest focused on organic-inorganic halide perovskites since 2012 derives from their unique optical and electrical properties, which make them excellent photovoltaic materials. Pb-based halide perovskite solar cells, in particular, currently stand at a record efficiency of ≈23%, fulfilling their potential toward commercialization. However, because of the toxicity concerns of Pb-based perovskite solar cells, their market prospects are hindered. In principle, Pb can be replaced with other less-toxic, environmentally benign metals. Sn-based perovskites are thus the far most promising alternative due to their very similar and perhaps even superior semiconductor characteristics. After years of effort invested in Sn-based halide perovskites, sufficient breakthroughs have finally been achieved that make them the next runners up to the Pb halide perovskites. To help the reader better understand the nature of Sn-based halide perovskites, their optical and electrical properties are systematically discussed. Recent progress in Sn-based perovskite solar cells, focusing mainly on film fabrication methods and different device architectures, and highlighting roadblocks to progress and opportunities for future work are reviewed. Finally, a brief overview of mixed Sn/Pb-based systems with their anomalous yet beneficial optical trends are discussed. The current challenges and a future outlook for Sn-based perovskites are discussed.

“无铅”钙钛矿:锡基钙钛矿太阳能电池的现状和未来前景。

自2012年以来,人们对有机-无机卤化物钙钛矿的关注极大,其独特的光学和电学特性使其成为出色的光伏材料。尤其是基于铅的卤化物钙钛矿太阳能电池,目前的效率达到创纪录的约23%,充分发挥了其商业化的潜力。然而,由于基于铅的钙钛矿太阳能电池的毒性问题,阻碍了它们的市场前景。原则上,铅可以用其他毒性较小,对环境无害的金属代替。因此,基于锡的钙钛矿由于其非常相似甚至是优越的半导体特性而成为最有前途的替代品。经过多年的努力,对锡基卤化钙钛矿进行了投资,终于取得了足够的突破,使它们成为卤化铅钙钛矿中的下一个竞争者。为了帮助读者更好地理解Sn基卤化物钙钛矿的性质,系统地讨论了它们的光学和电学性质。回顾了锡基钙钛矿太阳能电池的最新进展,主要关注薄膜的制造方法和不同的器件架构,并着重指出了进展的障碍和未来工作的机会。最后,对混合的基于Sn / Pb的系统及其异常但有益的光学趋势进行了简要概述。讨论了锡基钙钛矿的当前挑战和未来前景。系统地讨论了它们的光学和电学性质。回顾了锡基钙钛矿太阳能电池的最新进展,主要关注薄膜的制造方法和不同的器件架构,并着重指出了进展的障碍和未来工作的机会。最后,对混合的基于Sn / Pb的系统及其异常但有益的光学趋势进行了简要概述。讨论了锡基钙钛矿的当前挑战和未来前景。系统地讨论了它们的光学和电学性质。回顾了锡基钙钛矿太阳能电池的最新进展,主要关注薄膜的制造方法和不同的器件架构,并着重指出了进展的障碍和未来工作的机会。最后,对混合的基于Sn / Pb的系统及其异常但有益的光学趋势进行了简要概述。讨论了锡基钙钛矿的当前挑战和未来前景。
