Abstract
The present disclosure relates to a solar cell that includes a first layer that includes a semiconductor and a second layer that includes at least one of an oxide, a carbide, a nitride, a fluoride, and/or a sulfide, where the second layer covers a surface of the first layer, the second layer has a thickness between about 400 nm and about 10 μm, and the solar cell retains at least 95% of a starting power-conversion-efficiency (PCE) after exposure to a proton fluence of about 1E15 cm−2 for protons having an energy between greater than zero KeV per proton and less than or equal to 0.05 KeV per proton.
