Abstract

Perovskite solar cells (PSCs) have the potential to produce solar energy at a low cost, with flexibility, and high power conversion efficiency (PCE). However, there are still challenges to be addressed before mass production of PSCs, such as prevention from degradation under external stresses and the uniform, large-area formation of all layers. Among them, the most challenging aspect of mass production of PSCs is creating a high-quality perovskite layer using environmentally sustainable processes that are compatible with industry standards. In this review, we briefly introduce the recent progresses upon eco-friendly perovskite solutions/antisolvents and film formation processes. The eco-friendly production methods are categorized into two: (1) employing environmentally friendly solvents for perovskite precursor ink/solution, and (2) replacing harmful, volatile antisolvents or even limiting their use during the perovskite film formation process. General considerations and criteria for each category are provided, and detailed examples are presented, specifically focused on the works have done since 2021. In addition, the importance of controlling the crystallization behavior of the perovskite layer is highlighted to develop antisolvent-free perovskite formation methods.

高效钙钛矿太阳能电池生态友好型制造工艺研究进展

钙钛矿太阳能电池(PSCs)具有低成本、灵活性和高功率转换效率(PCE)的潜力。然而，在psc大规模生产之前，仍有一些挑战需要解决，例如防止在外部应力下降解和所有层的均匀，大面积形成。其中，大规模生产psc最具挑战性的方面是使用符合行业标准的环境可持续工艺制造高质量的钙钛矿层。本文简要介绍了近年来环保钙钛矿溶液/反溶剂和成膜工艺的研究进展。环保生产方法分为两大类:(1)采用环保溶剂制备钙钛矿前驱体油墨/溶液;(2)在钙钛矿成膜过程中替代有害的、易挥发的抗溶剂，甚至限制其使用。提供了每个类别的一般考虑因素和标准，并提供了详细的示例，特别关注自2021年以来完成的工作。此外，还强调了控制钙钛矿层的结晶行为对于开发无溶剂钙钛矿形成方法的重要性。图形抽象
