Design of Light Condenser Optical System Based on Membrane Mirror with High Power Condenser Ratio

Light Condenser Optical system based on membrane mirror with high power condenser ratio is designed. This paper analyzed the impact of rope net structure prestress distribution on surface figure accuracy and its impact on the focal plane illuminance. Because GaAs cell performance will be affected by temperature, this paper also calculated the surface temperature of the gallium arsenide cells and analyzed its impact on the conversion efficiency. Appropriate method is proposed to resolve the problem. This research on photovoltaic generation has certain reference value particularly for space solar power system.
