本文所报道的用于聚光太阳电池的菲涅耳透镜的设计特点是:菲涅耳齿设置征背光面,齿距较宽,对透镜边角的齿采用散焦和倒置法,对透镜中间部分的齿采用散焦法,透镜中心与太阳电池面积相等部分不设菲涅耳齿。经过测定,所制作的透镜符合聚光太阳电池的要求。 The design features of the Fresnel lens for concentrating solar cells reported in this paper are as follows: Fresnel teeth set the back surface, wide pitch, the defocus and inversion of the teeth on the corner of the lens, Part of the tooth using defocus method, the lens center and the solar cell area equal to no Fresnel teeth. After determination, the lens produced by the condenser solar cells meet the requirements.
