摘　　要：利用非成像光学方法,设计了适用于聚光光伏系统的高倍聚光器。为了提高电池表面的照度均匀性,在设计中引入匀光器,并综合优化容忍角和光通过率等关键参数。设计完成的带有匀光器的TIR-R(Total Internal Reflection-Refraction)太阳能聚光器,可使电池表面光照最大强度不大于平均值的2倍,容忍角达到1.53°,聚光倍数为1256倍。仿真表明,太阳光发散角可改善光照均匀性,而聚光器材料色散则主要造成容忍角减小。A high-concentration photovohaic system was designed using non-imaging optics. To improve the irradiance uniformity surface of on solar cell, a homogenizer was introduced, and Total Internal Reflection Refraction （TIR-R） concentrator with concentration ratio of 1256 x and acceptance angle of 1.53° was designed, with the highest irradiance intensity is less than twice the average on the cell surface. Simulations also reveal that the divergence angle of the sun can improve the irradiance uniformity, while the dispersion of the concentrator material mainly makes the acceptance angle decrease.
