Solar photovoltaic power generation with high-concentration-ratio system

研究了基于三结型(InGaP/InGaAs/Ge)高效太阳能电池的太阳能光伏发电的高倍聚光系统。该系统采用高次非球面光学玻璃卡塞格林系统,运用Zemax和Tracepro光学设计软件完成200～500倍太阳能聚光系统的设计,同时设计了单片型高倍太阳能聚能光学组件,用热压成型方法研制了太阳能聚能透镜(副镜)。采用16个性能相同的聚光光学组件和相同数量的三结型太阳能电池组成高倍聚光型太阳能光伏组件,极大地提高了聚光比,为太阳能光伏发电的高倍聚光器设计提供参考和依据。

Based on three-junction（InGaP/InGaAs/Ge） high efficient solar cell,the PV conversion of a high power optical system was achieved,which used high-order precision aspheric Cassegrain system.Two solar PV systems of 200-500 times concentration-ratio were obtained with Zemax and Tracepro.One of them was a monolithic system with solar condenser component.Secondary mirror of high power solar PV system was manufactured using hot-press forming.16 sets of optical concentration elements combined with three-junction（InGaP/InGaAs/Ge） high efficient solar cells of the same volumes were used to form a complete unit of a high power solar condenser PV system.The solar concentration ratio is greatly increased,which provides a good reference for the design of solar PV power generation and high-convergence-ratio facilities.
