摘　　要：通过聚光等形式提高光能密度,减少光伏材料的使用量,有助于保护环境和节约能源。文章提出一种新型聚光器设计方案,其在分析太阳张角对光路影响基础上,对聚光器模型进行改进,并得到接收器上反射光线分布规律。根据节省材料比和聚光硅电池效率选取聚光器参数,建立聚光器三维模型,在TracePro软件中进行仿真,得到接收器表面的辐照度分布和总光通量,与传统光伏聚光器聚光效果对比,验证聚光器模型的有效性,为聚光光伏发电系统的实物设计奠定了理论基础。Increasing light energy density through concentrating and other forms,reducing the amount of photovoltaic materials used,will help protect the environment and save energy.This paper proposes a concentrator design scheme.Based on the analysis of the influence of the sun’s opening angle on the light path,the concentrator model is improved,and the distribution of reflected light on the receiver is obtained.According to the material saving ratio and the efficiency of the concentrating silicon cell,the parameters of the concentrator are selected.The three-dimensional model of the concentrator is established,and the simulation is carried out in the TracePro to obtain the irradiance distribution and total luminous flux of the receiver surface.The concentrating effect of the concentrator verifies the validity of the concentrator model,laying a theoretical foundation for the physical design of the concentrating photovoltaic power generation system.
