Claim:
1. A method of manufacturing a photovoltaic device comprising a semiconductor light absorption layer (SLAL), comprising: obtaining a stack of layers comprising a substrate and an electrode layer; depositing, on the stack, a solvent, a plurality of semiconducting particles, and a plurality of additive molecules, wherein the plurality of semiconducting particles comprises at least one selected from a group consisting of: cadmium telluride, copper indium gallium selenide, cadmium zinc telluride, and copper zinc tin selinium/sulfide; evaporating the solvent from the stack by applying heat; sintering the stack to form the SLAL; depositing a transparent electrode on the SLAL; depositing a grid electrode of a conducting material on the transparent electrode; and eliminating, after evaporating the solvent, a portion of the plurality of additive molecules by applying ultraviolet (UV) light.
