中文摘要：

设计并搭建了两种不同集热结构的PV/TT系统，试验采集了环境、温度、功率等参数，获得了两个系统的温度特性、热效率、发电效率。试验结果表明，PV/T系统效率主要受环境因素影响，集热结构对其性能也产生不同程度的影响。无空腔PV/T系统的冷却效果好于有空腔系统，发电效率较高；有空腔PV/T系统的热效率较高，一次能源节约牢略高于无宅腔系统。

英文摘要：

Two different sets of thermal structure of PV/T system are designed and built. Environmental parameters, temperature, power and other parameters are collected, the data is processed and the temperature property, thermal efficiency and electric efficiency of two systems are obtained. The analysis indicates that the efficiency of PVFF system is mainly influenced by environmental factors, air cavity thermal structure will have different effects on its performance. The cooling effect of the system without air cavity is better than that of air cavity system, and the electric efficiency of the system without air cavity is higher than that of air cavity system. The thermal efficiency of the air cavity system is greater. The primary energy saving efficiency of the air cavity system is slightly higher than that of the system without air cavity.
