Energy shortage has become a global issue in the twenty-firt century, as energy consumption grows at an alarming rate as the fossil fuel supply exhausts. Perovskite solar cells (PSCs) are a promising photovoltaic technology that has grown quickly in recent years. Its power conversion efficiency (PCE) is comparable to that of traditional silicon-based solar cells, and scale-up costs can be substantially reduced due to its utilization of solution-processable fabrication. Nevertheless, most PSCs research uses hazardous solvents, such as dimethylformamide (DMF) and chlorobenzene (CB), which are not suitable for large-scale ambient operations and industrial production. In this study, we have successfully deposited all of the layers of PSCs, except the top metal electrode, under ambient conditions using a slot-die coating process and nontoxic solvents. The fully slot-die coated PSCs exhibited PCEs of 13.86% and 13.54% in a single device (0.09 cm) and mini-module (0.75 cm), respectively.
能源短缺已成为21世纪的全球性问题，随着化石燃料供应枯竭，能源消耗正以惊人的速度增长。钙钛矿太阳能电池（PSC）是一种很有前途的光伏技术，近年来发展迅速。其功率转换效率（PCE）与传统硅基太阳能电池相当，并且由于采用可溶液加工的制造工艺，可大幅降低扩大规模的成本。然而，大多数PSC研究使用危险溶剂，如二甲基甲酰胺（DMF）和氯苯（CB），这些溶剂不适用于大规模的环境作业和工业生产。在本研究中，我们使用狭缝式涂布工艺和无毒溶剂，在环境条件下成功沉积了除顶部金属电极外的所有PSC层。全狭缝式涂布的PSC在单个器件（0.09平方厘米）和微型模块（0.75平方厘米）中的PCE分别为13.86%和13.54%。
