Abstract
Various embodiments disclosed herein comprise a photovoltaic device of improved efficiency. The photovoltaic device comprises a photovoltaic material, a reflective conductor, a total-internal-reflection surface and a microstructure. The microstructure reflects light so that some of the reflected light is incident upon the total-internal-reflection surface at an angle greater than the critical angle. In some embodiments, the photovoltaic device has a photovoltaic material, a reflective conductor, and a surface forward the conductor configured to redirect light rays directed toward the conductor such that redirected light is instead incident on the photovoltaic material. Various embodiments include a method of manufacturing a photovoltaic device of improved efficiency. Other embodiments are also described.
