摘要: 采用新型石墨烯材料用于光伏组件背板散热,以提高光伏组件能量转换效率。在硅太阳电池组件基础上分别设计并制作普通石墨烯薄膜组件以及石墨烯肋片复合结构组件,建立2种石墨烯光伏组件的热力学模型,搭建石墨烯组件散热性能测试平台进行实验研究,此外进行组件室外光伏电站的性能测试。实验结果表明,添加石墨烯及肋片能增强光伏组件散热性能和提高组件输出功率;在室内模拟的晴天气象条件及辐照度高的情况下,石墨烯肋片复合组件的散热性能提升较为显著。通过室外测试,石墨烯肋片复合组件的功率及发电量相比于普通光伏组件分别提高0.5%～1.15%和0.97%。Abstract: This paper used graphene material to promote heat dissipation performance for photovoltaic（PV） module,thus improving the energy conversion efficiency of PV modules.Based on common PV modules,two kinds of PV modules with graphene film and graphene fin composite structures were designed and fabricated.Thermodynamic models of these two kinds of graphene PV modules were established.The heat dissipation performance of graphene PV modules was carried out on a test platform,and the outdoor experiment was also investigated.The experimental results showed that the addition of graphene material and fin can enhance the heat dissipation performance of PV module and the output power of modules were increased.In the case of high irradiance,the heat dissipation performance of PV modules with the graphene fin composite component is significantly improved.In outdoor tests,the power and the generated energy of graphene PV modules were increased by 0.5%-1.15% and 0.97% respectively compared to ordinary PV modules.
