Abstract
A solar cell structure using either a dye-sensitized or organic absorber is provided with a diffraction grating on at least one side to enhance the travel of first order diffraction components through the photo sensitive material. A two-sided cell uses diffraction gratings both top and bottom wherein the periodic diffraction elements of one grating are shifted by one-quarter of the grating period relative to the other.
