The low power-conversion efficiency (PCE) and reproducibility reported to date for roll-to-roll (R2R)-fabricated perovskite solar cells (PSCs) results from difficulty in controlling perovskite film quality. Here, we present a systematic comparison of the hot-deposition method, which induces crystal-growth-driven (CGD) film formation, and the anti-solvent method, which induces nucleation-driven (ND) film formation, for one-step perovskite film formation. Perovskite films produced by the two methods show markedly different micro-structural and optoelectronic properties; however, PCEs of CGD-type PSCs are only marginally lower than those of ND-type PSCs. Importantly, the average performance of PSCs incorporating a CGD-type perovskite layer is independent of humidity during fabrication and displays improved stability and reproducibility, prompting further investigation of upscaling potential. R2R-produced PSCs on plastic substrate with four slot-die-coated functional layers show superior reproducibility and micro-structural, optoelectronic, and photovoltaic properties comparable with those of glass-based PSCs, indicating excellent promise for translation to a manufacturing process.

在室温条件下可复制钙钛矿型太阳能电池卷到卷制造的实验室到工厂研究

迄今为止报道的卷对卷(R2R)制造的钙钛矿太阳能电池(PSC)的低功率转换效率(PCE)和可重复性是由于难以控制钙钛矿薄膜质量而导致的。在这里,我们对一步法钙钛矿的热沉积方法(诱导晶体生长驱动(CGD)成膜)和反溶剂方法(诱导成核驱动(ND)成膜)进行了系统的比较。成膜。两种方法生产的钙钛矿薄膜显示出明显不同的微观结构和光电性能。但是,CGD型PSC的PCE仅略低于ND型PSC的PCE。重要的是,掺入CGD型钙钛矿层的PSC的平均性能与制造过程中的湿度无关,并显示出更高的稳定性和可重复性,促使进一步研究扩大规模的潜力。R4R生产的具有四个狭缝模头涂覆的功能层的塑料基板上的PSC具有与玻璃基PSC相当的可重复性以及微结构,光电和光伏特性,这预示了向生产过程转化的巨大希望。
