THE CONCENTRATING PV/T MODULE WITH THE FUNCTION OF TEMPERATURE CONTROL

采用热传导原理并结合ANSYS Workbench温度场分析,研制一种带温控功能的聚光PV/T组件。经实验测试,在通过聚光器获得的5倍太阳辐射强度下,该PV/T组件可有效解决聚光晶硅电池片的散热问题,其工作时光电转换效率大于12%;同时,可获得温度约为60℃的热水;聚光PV/T组件综合转换效率可达到65.8%,实现了高效和低成本太阳能光电光热综合利用。

Based on the heat transferring theory and combined with the analysis of temperature distribution under the ANSYS Workbench, a kind of concentrating photovoltaic thermal （PV/T） module with the function of temperature control was developed. The experiments with the module showed that under the condition of five times solar radiation intensity which was got with the light focusing device, the heat dissipation problems in crystal silicon solar cells can be solved efficiently, and the photoelectric conversion efficiency of solar cells would always be more than 12%. At the same time, hot water having temperature about 60 ℃ is obtained. That is, the overall conversion efficiency of the concentrating PV/T module is more than 65.8%, and it means that it would utilize PV/T with a high efficient and low-costing way.
