【Abstract】 A hybrid concentrating photovoltaic system is proposed on the basis of Fresnel lens,which has the converging characteristic to get the light collected to a point. The system uses the parabolic reflector to get parallel light simultaneously. The parallel light is obtained by a point light source reflecting through parabolic reflector,and the point light should be placed on the focus of the parabolic reflector. Preliminary simulation data of the entire concentrating photovoltaic system will be obtained by Zemax. Then the condenser system can be optimized and improved in reference to the simulation results. The comparative analysis shows that the improved system achieves a higher collection efficiency and better utilization.更多还原
