MoS2—an integrated protective and active layer on n+p-Si for solar H2 evolution

Author affiliations

Abstract

A new MoS2 protected n+p-junction Si photocathode for the renewable H2 evolution is presented here. MoS2 acts as both a protective and an electrocatalytic layer, allowing H2 evolution at 0 V vs. RHE for more than 5 days. Using a MoSx surface layer decreases the overpotential for H2 evolution by 200 mV.
