The development of high-performance bifunctional electrocatalysts that can catalyze both anodic oxygen evolution (OER) and cathodic hydrogen evolution (HER) is considered to be a promising way to realize hydrogen economy. However, the slow kinetic process for OER and the unsatisfied long-term...

Charge-transport layer engineering is proved to be as important as the optimization of perovskite light harvesting layer in achieving high power conversion efficiency for the inverted perovskite solar cells ( p-i-n PSCs ). This work mainly focuses on electron transport interface engineering and...
