BPN579: Top-Down and Bottom-Up Approaches to Anti-Reflective Templates for Efficient Photoelectrochemical Solar-to-Fuel Conversion

Due to tightened regulations on environmental control and high demand on clean fuel, there is great interest in developing a method whose process and product are both eco-friendly. Hydrogen is a fuel of high quality and zero emission. Hydrogen can be directly produced by splitting water into H2 and O2. This project focuses on photochemical splitting of water using solar energy and InP as the photocatalyst. In an effort to enhance the efficiency, the InP is textured to have very low reflectivity.
