Reducing Module Soiling with Scalable and Robust Photocatalytic Coatings

closed

The project will make and scale multilayer, anti-reflective and anti-soiling coatings for solar glass. These coatings will be deposited by a technique that sprays dry nanoparticles. The coatings have the potential to increase annual energy yield by reducing the loss of energy output that results when light gets reflected or when dirt lands on the modules. They will also reduce operation and maintenance costs because the modules won't require as much cleaning. The team will perform outdoor testing in collaboration with the National Renewable Energy Laboratory.
