Abstract

GaAs p-n junction layers were grown via Molecular Beam Epitaxy, fabricated into solar cell fabricated into a solar cell by depositing gold contact pads via UV lithography and electron beam deposition and characterized by taking its I-V curve. By varying solar cell thickness, which in turn affects the dopant and diffusion length via chemical etching, allowed the enhancement of the solar cell’s minimum efficiency when fabricated.
