The electron transport layer/perovskite interfaces play a crucial role in facilitating efficient charge transfer and minimizing recombination losses, which are key factors for achieving high power conversion efficiency (PCE) in perovskite solar cells (PSCs). Herein, a novel ionic liquid called 2-bro...
