Photoelectrochemical water splitting is one of the viable approaches to produce clean hydrogen energy from water. Herein, we report MoS 2 /Si-heterojunction (HJ) photocathode for PEC H 2 production. The MoS 2 /Si-HJ photocathode exhibits exceptional PEC H 2 production performance with a maximum photocurrent density of 36.33 mA/cm 2 , open circuit potential of 0.5 V vs. RHE and achieves improved long-term stability up to 10 h of reaction time. The photocurrent density achieved by MoS 2 /Si-HJ photocathode is significantly higher than most of the MoS 2 coupled Si-based photocathodes reported elsewhere, indicating excellent PEC H 2 production performance.
