Abstract

An efficient and intrinsically safe bias-free solar-driven water-splitting device composed of perovskite light harvesters, Earth-abundant catalysts, and a bipolar membrane is demonstrated. Overall, 10 mA cm−2 current density with 1.63 V bias voltage for electrochemical water splitting and 12.7% solar to hydrogen conversion efficiency for solar-driven water splitting are achieved.
