| 摘要: 近年来，钙钛矿光伏电池（PSCs）取得了突飞猛进的发展，迄今最高认证光电转换效率达到25.7%，但是钙钛矿材料常使用有毒的重金属元素铅，对环境和人体都有极大的危害，不利于其实际应用，因此发展无铅PSCs受到越来越多的关注。锡基钙钛矿材料具有优异的光电性质，特别是带隙窄、载流子迁移率高和激子复合能低，是无铅钙钛矿中最具有潜力的材料。反式（p-i-n型）锡基PSCs由于低迟滞效应、可低温制备及低成本等优点获得普遍关注，取得了一系列重要突破，目前最高效率已经突破14%，具有巨大的发展潜力。鉴于反式锡基钙钛矿太阳能的迅速发展，本文系统综述了反式锡基PSCs制备及稳定性研究进展，尤其关注反式锡基PSCs的界面修饰、锡基钙钛矿材料性能、构筑高质量锡基钙钛矿薄膜的方法以及提高稳定性的策略，并讨论了锡基PSCs的前景展望。 | |

| Abstract: In recent years, perovskite solar cells (PSCs) have achieved rapid development with the maximum certified power conversion efficiency (PCE) up to 25.7%, which is comparable with the advances obtained for silicon and thin-film solar cells. However, the involvement of lead, which is a cumulative toxicant to human bodies, hampers the pace of their future commercial application. Therefore, it is crucial to seek a new path to reduce or eliminate Pb from PSCs and replace it with other environmentally friendly elements. Recently, the development of lead-free PSCs has attracted great attentions. Tin-based perovskite materials with excellent photoelectric properties are thus by far the most promising alternative. The p-i-n inverted tin-based PSCs have developed rapidly in recent years, which represented an important breakthrough in the field. Their main advantages include low-temperature fabrication, cost-effectiveness, and suppressed hysteresis behavior, alongside a competitive power conversion efficiency of up to 14.8%. Though numerous research efforts have been devoted to inverted Sn-based PSCs, the PCE of these devices still lag far behind Pb-based PSCs. The rapid development of inverted Sn-based PSCs prompted us to review the current progress of inverted p-i-n Sn-based PSCs, focusing mainly on the aspects involving on features p-i-n Sn-based PSCs, interface layers, properties of Sn perovskites, and fabrication of a high-quality Sn perovskite active layer, highlighting the obstacles to further progress and opportunities for future work. | |
