Photoelectrochemical (PEC) water splitting using photovoltaic cell is considered an ideal path for hydrogen production. However, its application limited by the low efficiency of photoelectrode surface. Herein, we successfully fabricated efficient composite evolution reaction (HER) catalysts onto silicon heterojunction (SHJ) solar via solution‐processed methods under mild conditions. The nanoheterostructured HER consist crystalline Ni 3 S 2 , Cu, and Ce(OH) which display excellent performance due to synergistic effect constituted components. As a result, optimized photocathode achieves high photocurrent −37.8 mA cm −2 at 0 V vs. Reversible electrode applied bias photon‐to‐current (ABPE) 8.5 ± 0.1% simulated AM 1.5G one‐sun illumination more than 120 h continuous splitting. This study offers novel insights into designing economical large‐scale PEC devices.
