摘要

The last few years witnessed exceptional advancement of organohalide perovskite photovoltaics owing to their intriguing optoelectronic properties.The power conversion efficiency (PCE) of the state-of-art lab-scale perovskite solar cells (PSCs) has skyrocketed from 3.8％ to a certified value of 22.1％ (aperture area of 0.046 cm2) [1],approaching the stage where up-scaling to commercial dimensions is an imperative,Recently,some promising results have been demonstrated for perovskite device with larger active area of ca.1 cm2.By using a vacuum-flash assisted solution process,Gr(a)tzel and co-workers [2] reported a certified PCE of 19.6％ for mesoscopic PSCs with an aperture area exceeding 1 cm2.
