摘　　要：设计了三种槽式太阳能电池聚光反射器模型:梯形、圆弧形和抛物线形,在光学软件Fred中建立模型,利用软件提供的光线跟踪方法,针对其有、无跟踪太阳两种情况进行优化,得出了在这两种情况下,不同几何聚集比(C=1.5,2,2.5,3,3.5)时的最佳形状参数(倾角θ或高底比Hd),为实际生产加工过程提供了指导,最后对比了三种聚光反射结构的优缺点。Three trough focus reflectors used by solar cell were designed. The shapes are trapezium, arc and parabola. There models were created in the optical software Fred. Aiming at the situation that tracing solar or not, and using the ray tracing method offered by the software, the best shape parameter （angle θ or Hd） was obtained corresponding the different geometry collect ratio （C= 1.5, 2, 2.5, 3, 3.5）. The result can be used in the manufacture process. At last, the advantages and disadvantages of three models were discussed.
