Abstract

A solar cell with a luminescent antireflective coating (24, 26) is provided, preferably consisting of a first manganese-doped layer (24) of zinc sulphide and a second layer (26) of magnesium fluoride. The luminescence has the effect that the radiation in the UV range that is largely unused in the case of conventional solar cells is converted into light of a longer wavelength, whereby the efficiency is increased.
