针对由聚光器与光伏光热(Photovoltaic/Thermal,PV/T)器件构成的太阳能热电联供组件,建立太阳能流在组件中传递的光电热耦合理论模型,在稳态条件下,用理论模型计算组件电热输出性能并进行实验检测.结果表明:理论计算组件光电效率为13.1％,光热效率为53.0％;实验检测组件光电效率为13.0％,光热效率为52.8％,理论与实验结果吻合较好,说明理论模型计算准确.研究过程发现,环境温度对组件光热效率影响较小,原因在于聚光器替代大部分PV/T器件使得PV/T器件顶部热损失面积降低,进而降低了组件热损失.
Study on the Photovoltaic-thermal Coupling and Performance of Solar Thermal Photovoltaic Combined Modules
For solar thermal photovoltaic combined modules consisting of concentrators and photovoltaic/thermal(PV/T)devices,a theoretical model for photovoltaic-thermal coupling of solar energy flow within the module was established.Under steady-state conditions,the electrical and thermal output performance of the module was calculated using the theoretical model and experimentally verified.The results show that the theoretical calculated photovoltaic efficiency of the module is 13.1％,and its thermal efficiency is 53.0％,while the experimentally measured photovoltaic efficiency is 13.0％,and the thermal efficiency is 52.8％.The close match between theoretical and experimental results demonstrates the high accuracy of the theoretical model.During the study,it was found that the environmental temperature has minimal influence on the module's thermal efficiency,primarily because the concentrator replaces most of the PV/T devices,thereby reducing the top heat loss area of the PV/T device,and consequently reducing the thermal losses of the module.
