EcoEnergy, EarlyView.A bifunctional molecular bridge using 4‐guanidinobutanoic acid (GCC) is constructed to comprehensively tailor the buried interface of PSCs. By passivating oxygen vacancies, optimizing energy‐level matching, and regulating perovskite crystallization, this strategy simultaneously boosts the power conversion efficiency to 25.37% (20.01% for 13.4 cm2) and ...
