摘　　要：传统光伏发电系统普遍存在发电效率较低、光能利用率较低、大部分光子直接产热等问题。设计出一种利用菲涅尔透镜结合ORC余热回收系统的双球腔光伏发电系统,以路灯为搭载体进行模型搭建以及动模实验数据采集。曲面菲涅尔透镜实现大范围聚光,有机工质吸收发电过程余热,实现光伏+光热双发电效应储能。经实物动模实验检验得到发电系统功率显著提升,模拟计算功率平均可达400W,整体发电效率达46.68%,为单一传统光伏板效率的1.714倍。Traditional photovoltaic power generation systems generally have problems such as poor power generation efficiency,low utilization rate of light energy,and direct heat production of most photons.In this paper,a dual-sphere cavity photovoltaic power generation system using Fresnel lens combined with ORC waste heat recovery system is innovatively designed for model construction and dynamic mode experimental data acquisition.The curved Fresnel lens realizes a large range of light concentration,the organic working medium absorbs the waste heat of the power generation process,and realizes the photovoltaic+photovoltaic dual power generation effect energy storage.According to the experimental test of the physical moving mode,the power of the power generation system is significantly improved.The average simulated and calculated power can reach 400W,and the overall power generation efficiency reaches 46.68%,which is 1.714 times of the efficiency of a single traditional photovoltaic panel.
