High-performance large-area perovskite photovoltaic modules

Perovskite solar cells(Pero-SCs)exhibited a bright future for the next generation of photovoltaic technology because of their high power conversion efficiency(PCE),low cost,and simple solution process.The certified laboratory-scale PCE has reached 25.7%referred to small scale(<0.1 cm^(2))of Pero-SCs.However,with the increase of the area to module scale,the PCE drops dramatically mainly due to the inadequate regulation of growing large-area perovskite films.Therefore,there is a dire need to produce high-quality perovskite films for large-area photovoltaic modules.Herein,we summarize the recent advances in perovskite photovoltaic modules(PPMs)with particular attention paid to the coating methods,as well as the growth regulation of the high-quality and large-area perovskite films.Furthermore,this study encompasses future development directions and prospects for PPMs.
