【Abstract】 In order to improve photoelectric conversion efficiency and reduce the cost of photovoltaic power generation,a new design method is proposed by using non-imaging optics principle: energy mapping design method. Designs and validates the energy mapping Fresnel PV concentration system. The diameter of Fresnel photovoltaic concentration system D = 226 mm; concentration ratio is 400; aspect ratio is 0. 8. Using the 3D software modeling and Trace Pro simulation analysis,the concentration efficiency of the energy mapping Fresnel PV concentration system is 90. 35% and the spot uniformity is 84. 17% ,it improves the uniformity of the illumination distribution on the receiving surface,thereby the photoelectric conversion efficiency of the photovoltaic cell is improved.更多还原
