摘　　要：太阳能电池片是光伏发电系统的核心部件,其光学反射特性对光伏组件的发电效率和缺陷检测的研究有着重要的理论意义,但实际应用中难以对其直接观察与测量。本文依据菲涅尔定律与多层介质模型研究了光伏组件的光学传输过程。首先基于微面元理论建立太阳能电池片表面的双向反射传输模型;然后借助多层介质模型推导了太阳能电池板偏振双向反射分布函数(bidirectional reflectance distribution function,BRDF),通过偏振相机搭建光伏组件光学偏振特性观测平台并开展偏振实验。在此基础上,利用遗传算法从实验测量数据中反演模型的参量数值,并得出偏振度信息随观测角变化的仿真曲线。通过实验表明,本文提出的光学传输模型仿真值与实验观测数据能够较好的吻合。该模型为太阳能电池板表面缺陷检测提供新的理论参考。Solar cell is the core component of photovoltaic power generation system,their optical reflection characteristics have an important theoretical significance for the research of power generation efficiency and defect detection of PV module,but it is difficult to observe and measure them directly in practical applications.In this paper,the optical transmission process of PV module is studied based on Fresnel′s law and multilayer media model.Firstly,the bidirectional reflection transmission model of solar cell surface is established based on the microfacet theory.Then the polarization bidirectional reflection distribution function(BRDF) of the solar panel is derived with the help of multilayer media model,the optical polarization characteristics observation platform of PV module is built by polarization camera and polarization experiments are carried out.Based on the above mentioned model,the genetic algorithm is used to invert the model parameter from the experimental measurement data and the simulation curve of polarization information with the observation angle is derived.The results show that the experimental observation data of the optical transmission model proposed in this paper can be in good agreement with the simulated values,which provides a new theoretical reference for studying the defect detection of solar panel surfaces.
