||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.
