Constructing an n/n homojunction in a monolithic perovskite film for boosting charge collection in inverted perovskite photovoltaics

The suboptimal carrier dynamics at the perovskite/electron transport layer has largely limited the further performance enhancement of the state-of-the-art inverted p-i-n structured perovskite solar cells. Herein, we discovered that a simple surface modification of the perovskite film by a trivalent...
