摘　　要：基于薄膜光学和传热学原理,利用特定光学薄膜滤除紫外线,以及热循环系统降低太阳能电池工作温度,设计了光伏/光热综合利用的温度控制系统.在阐述温控系统工作原理及其设计思路的基础上,提出系统指标体系,分析环境温度以及光谱透过率对传热效率的影响,并提出合理的改进方法.应用TFCalc薄膜设计软件设计特定的光学薄膜,仿真结果表明,所设计的薄膜能反射一定带宽的紫外光谱.该温控系统对于当前广泛使用的太阳能光伏发电系统具有良好的实用价值.A temperature control system is designed based on the principle of thin film optics and heat transfer theory, it integrates the utilization of solar photovoltaic-thermal effect by using a specific optical thin film to eliminate the ultraviolet radiation and a thermal circulation system to reduce its working temperature. After deducing the operational principle and design ideas of such system, the index are advanced, and the influence factors of ambient temperature and spectral transmittance to the heat transfer efficiency are analyzed. And then, several reasonable improved methods are put forward. A professional thin-film design software named TFCalc is applied to design a particular optical thin film, simulation results show that the film can reflect a certain bandwidth of ultraviolet spectrum. The temperature control system has good practical value for the widely used photovoltaic power system.
