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.
