PHOTONIC CRYSTAL ENHANCED LIGHT TRAPPING SOLAR CELL
摘要
This invention relates to a high efficiency solar cell comprising: (a) a top surface of an anti-reflective coating layer; (b) an engineered photonic crystal material layer, (c) an active photovoltaic layer; (d) a photonic crystals with an integrated diffraction grating; (e) a metallic diffraction grating reflective layer, and (f) a metallic back reflector; whereby normally incident light striking the surface of the solar cell passes through the anti-reflective coating and the engineered photonic crystal material layer and is absorbed by active photovoltaic layer thereby generating electrical energy and obliquely incident light is reflected and diffracted by the engineered photonic crystal material layer, the one dimensional photonic crystal layer, the metallic grating reflective layer and the metallic back reflector to the active photovoltaic layer thereby generating electrical energy.
