This work demonstrates a novel three-dimensional pyramid-like graphene/p-Si Schottky junction photocathode for H2 production based on the unique advantages of excellent carrier transport, high transparency and superior corrosion protection of graphene. The formation of graphene/Si Schottky junctions with 3D architecture is a promising approach to improve the performance and durability of Si-based photoelectrochemical systems for water splitting or solar-to-fuel conversion.
