Scientists are discovering new ways for solar panels to work on overcast days. This work, posted as a featured article on the Office of Science's website, was supported in part by the following EFRCs: Light-Material Interactions in Energy Conversion (LMI) EFRC led by Ralph Nuzzo at the California Institute of Technology; Argonne-Northwestern Solar Energy Research Center (ANSER) EFRC led by Michael Wasielewski at Northwestern University; and the Center for Solar Fuels (UNC) led by Thomas Meyer at the University of North Carolina
