Enhanced Water Vapor Blocking for Solar Cells


Scientific Achievement

Working through DOE’s Bay Area Photovoltaic Consortium, researchers at the Molecular Foundry created an optically transparent composite that improves water vapor blocking by 3000 times.

Significance and Impact

Corrosion of solar cell electrical contacts by water is a leading cause of device failure.
