Photovoltaic Energy Factsheet | Center for Sustainable Systems
One of the key characteristics of a photovoltaic device is the ability to capture incident photons. Reflected light is uncaptured energy, and thus various antireflection (AR) schemes have been developed to raise the efficiency of solar cells. 1 Quarter-wavelength AR coatings have been widely used on the front surface, but their effectiveness typically depends on …
