Congratulations Ms Peng Wang for successful completion of her PhD thesis titled 'Anodized Cuprous Oxide Photocathodes for Solar Energy Conversion'. Hydrogen generation from photoelectrochemical water splitting under visible light has been considered as an effective way to make solar energy transportable and storable. Cu2O, a p-type semiconductor, has recently attracted extensive attention due to its relatively low cost, non-toxicity, and have a direct bandgap of 2.0 eV. However, the photocorrosion of Cu2O limits its application. Her project aims to develop highly stable Cu2O based photocathodes for solar energy conversion.

Below are list of Peng's work on the development of stable Cu2O photocathodes:
