Cu 2 O Photocathode with Faster Charge Transfer by Fully Reacted Cu Seed Layer to Enhance Performance of Hydrogen Evolution in Solar Water Splitting Applications

In this work, we study the effect of Cu2O film obtained from a fully reacted Cu seed layer as a photoelectrode in photoelectrochemical cells. The full reaction of the Cu layer shows an enhanced photocurrent density and improved efficiency in hydrogen evolution. The photocurrent density of textured Cu2O (0.58 mA cm(-2) at 0 V vs. RHE), wit...More
