Water Splitting: Creation of 3D Textured Graphene/Si Schottky Junction Photocathode for Enhanced Photo‐Electrochemical Efficiency and Stability (adv. Energy Mater. 29/2019)

In article number 1901022, Di-Yan Wang, Bing Joe Hwang, Chun-Wei Chen and co-workers demonstrate a novel three-dimensional pyramid-like graphene/p-Si Schottky junction photocathode for H2 production. The formation of graphene/Si Schottky junctions with a 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.
