Gas‐Assisted Spray Coating of Perovskite Solar Cells Incorporating Sprayed Self‐Assembled Monolayers (Adv. Sci. 14/2022)

Self‐Assembled Monolayers Carbazole‐based self‐assembled monolayers are becoming a dominant hole‐transporting layer in p‐i‐n perovskite solar cells, combining stability, efficiency, and low‐cost. In article number 2104848 by David G. Lidzey and co‐workers, spray coating and airbrush pen coating of MeO‐2PACz is used to fabricate high‐quality transport layers. This is combined with gas‐quenched spray‐coated perovskite layers, to realize solar cells with power conversion efficiencies in excess of 20%. [Image: see text]
