摘  要:本文设计了一种具有均匀聚光效果的紧凑式线性菲涅耳太阳能光伏系统,给出了紧凑式线性菲涅耳聚光器的设计方法。对完全型紧凑式线性菲涅耳聚光光伏系统进行了光学性能分析,分析结果表明,系统具有相对较高的聚光均匀性。当其他参数一定时,随着太阳电池放置高度由小变大,系统的几何聚光比和光场利用率存在最大值。对太阳光线的跟踪精度影响进行了分析,分析结果表明,使用现有太阳能跟踪装置条件下,完全型紧凑式线性菲涅耳聚光光伏系统的总相对光学效率可保持在88.5%以上。初步的光伏组件Ⅰ-Ⅴ特性测试结果表明,该聚光光伏系统的光电转换效率为15.9%。In this paper, a solar concentrating PV(CPV) system using compact linear Fresnel reflector(CLFR) with uniform solar concentration performance is designed. The design method of the CPV system is provided. The optical parameter analysis of the CPV system with CLFR-complete concentrator are carried out. The analysis results show that the CPV system has a relatively high solar concentration uniformity. When other parameters are settled, the concentration ratio and ground utilization ratio of the CPV system both have the maximum values with the solar panel height increased. The sun tracking accuracy effect is analyzed. The results show that the normalized overall optical efficiency of the CPV system can be higher than 88.5% when a normal sun-tracker is utilized. The results of preliminary Ⅰ-Ⅴ test show that the photoelectric conversion efficiency of the solar cell module is 15.9%.
