Abstract

The primary challenge for the commercialization of hybrid perovskite solar cells (PSCs) is their chemical and thermal instability as compared to Si devices. Herein, we demonstrate that PSCs spray-coated with polystyrene retain 80% of their efficiency after 40 hours immersed in water or at 95 °C.

在钙钛矿太阳能电池上喷涂聚苯乙烯增加热稳定性和耐湿性†
与硅器件相比,混合钙钛矿太阳能电池(PSCs)商业化的主要挑战是其化学和热不稳定性。在此,我们证明已经与聚苯乙烯spray-coated保留80%的效率在40小时沉浸在水或95°C。
