Abstract

ABSTRACT Perovskite solar cells are promising candidates for next-generation photovoltaic devices with certified power-conversion efficiency for single-junction perovskite-based devices exceeded 25%. However, it remains challenging to fabricate a large-area and dense perovskite film using solution-based deposition methods. This is due to perovskite wet films being highly sensitive and unstable, and thus having only a narrow processing window. There is therefore a demand for ways to expand the processing window in the fabrication of perovskite films. Herein, we systematically review research on the role of precursor solutions and antisolvents during the perovskite formation process, and reveal the fundamental factors governing the width of the perovskite film-processing window. Then, we give an overview of current strategies for enlarging the processing window, which includes solvent and antisolvent engineering strategies. We conclude by summarizing current challenges in the development of perovskite solar modules with a wide processing window and provide perspectives for future development.

拓宽钙钛矿太阳能电池加工窗口的策略：溶剂/反溶剂作用的综述

摘要钙钛矿太阳能电池是下一代光伏器件的候选电池，单结钙钛矿基器件的功率转换效率超过25%。然而，使用基于溶液的沉积方法制备大面积和致密的钙钛矿膜仍然具有挑战性。这是由于钙钛矿湿膜高度敏感和不稳定，因此只有狭窄的处理窗口。因此，需要在钙钛矿膜的制造中扩大处理窗口的方法。在此，我们系统地回顾了前体溶液和反溶剂在钙钛矿形成过程中的作用的研究，并揭示了控制钙钛矿膜加工窗口宽度的基本因素。然后，我们概述了目前扩大加工窗口的策略，包括溶剂和反溶剂工程策略。最后，我们总结了目前开发具有宽加工窗口的钙钛矿太阳能组件的挑战，并为未来的发展提供了前景。
