||Hydrogen is a promising, environmentally-friendly fuel source for replacing fossil fuels in transportation and stationary power
applications. Currently, most hydrogen is produced from non-renewable sources including natural gas, oil, and coal.
Photoelectrochemical (PEC) water splitting is a new renewable energy technology that aims to generate hydrogen from water using
solar energy. When light is absorbed by the photocatalyst, an electron-hole pair is generated that interacts with water molecules in
a surface reduction-oxidation reaction to decompose the water into hydrogen and oxygen. The current challenge in PEC water
splitting is finding low-cost, stable materials with good visible light absorption and high efficiency for water splitting. Silicon has
demonstrated promising capabilities as photocatalysts due to its high visible light absorption, low cost, and high abundance. This
project aims to improve the performance of silicon for water splitting by developing new high-surface area silicon photoelectrodes
using chemical vapor deposition silicon.
