近年来，有机-无机金属卤化物钙钛矿单结太阳能电池因其高达23.7%的创纪录功率转换效率（PCE）和低成本的制造工艺而备受关注。除了单结器件外，低温溶液可加工性和带隙可调性使金属卤化物钙钛矿成为制造串联太阳能电池的理想候选者。串联太阳能电池结合了宽带隙钙钛矿顶部电池和基于混合锡(Sn)-铅（Pb）钙钛矿或不同材料（如硅（Si）或铜铟硒化镓（CIGS））的低带隙底部电池，为实现比单结电池的Shockley-Queisser （SQ）辐射效率限制（~ 33%）更高的pce提供了非凡的机会。本文综述了宽（1.7 ~ 1.9 eV）和低带隙（1.1 ~ 1.3 eV）钙钛矿单结电池的制备及其在串联电池中的应用研究进展。本文将讨论宽带隙和低带隙单结电池的主要挑战和问题。我们将调查目前最先进的钙钛矿串联电池，并讨论钙钛矿串联电池的局限性和挑战。最后，对钙钛矿串联太阳能电池的未来发展进行了展望。
Organic-inorganic metal halide perovskite single-junction solar cells have attracted great attention in the past few years due to a high record power conversion efficiency (PCE) of 23.7% and low-cost fabrication processes. Beyond single-junction devices, low-temperature solution processability, and bandgap tunability make the metal halide perovskites ideal candidates for fabricating tandem solar cells. Tandem solar cells combining a wide-bandgap perovskite top cell and a low-bandgap bottom cell based on mixed tin (Sn)-lead (Pb) perovskite or a dissimilar material such as silicon (Si) or copper indium gallium selenide (CIGS) offer an extraordinary opportunity to achieve PCEs higher than Shockley-Queisser (SQ) radiative efficiency limits (∼33%) for single-junction cells. In this review, we will summarize recent research progress on the fabrication of wide- (1.7 to 1.9 eV) and low-bandgap (1.1 to 1.3 eV) perovskite single-junction cells and their applications in tandem cells. Key challenges and issues in wide- and low-bandgap single-junction cells will be discussed. We will survey current state-of-the-art perovskite tandem cells and discuss the limitations and challenges for perovskite tandem cells. Lastly, we conclude with an outlook for the future development of perovskite tandem solar cells.
