METHOD FOR IMPROVING PV AESTHETICS AND EFFICIENCY

摘要

Various embodiments disclosed herein comprise a photovoltaic device of improved efficiency. The photovoltaic device comprises a photovoltaic material (203), a reflective conductor (602), a total-internal-reflection surface (606) and a microstructure (601). The microstructure (601) reflects light so that some of the reflected light is incident upon the total-internal-reflection surface (606) at an angle greater than the critical angle. In some embodiments, the photovoltaic device has a photovoltaic material (203), a reflective conductor (602), and a surface (701) forward the conductor (602) configured to redirect light rays directed toward the conductor (602) such that redirected light is instead incident on the photovoltaic material (203). Various embodiments include a method of manufacturing a photovoltaic device of improved efficiency. Other embodiments are also described.
