Perovskite quantum dots are a competitive candidate for next-generation solar cells owing to their superior phase stability and multiple exciton generation effects. However, given the voltage loss in perovskite quantum dot solar cells (PQDSCs) is mainly caused by various surface and interfacial defects and the energy band mismatch in the devices, tremendous achievements have been made to mitigate the loss of PQDSCs. Herein, we elucidate the potential threats that hinder the high of PQDSCs. Then, we summarize recent progress in minimizing open-circuit voltage () loss, including defect manipulation and device optimization, based on band-alignment engineering. Finally, we attempt to shed light on the methodologies used to further improve the performance of PQDSCs.
钙钛矿量子点因其优异的相稳定性和多激子产生效应，是下一代太阳能电池的有力候选材料。然而，鉴于钙钛矿量子点太阳能电池（PQDSCs）中的电压损失主要由各种表面和界面缺陷以及器件中的能带失配引起，人们已经在减轻PQDSCs的损失方面取得了巨大成就。在此，我们阐明了阻碍PQDSCs高[此处原文缺失具体内容]的潜在威胁。然后，我们总结了基于能带对准工程在最小化开路电压（）损失方面的最新进展，包括缺陷操纵和器件优化。最后，我们试图阐明用于进一步提高PQDSCs性能的方法。
