Abstract: A novel air/water-cooled PV/T integrated module is proposed in this paper. Two sets of test platforms are set up to conduct the air-cooled,water-cooled and air/water-cooled mode experiments on the PV/T module to investigate the performance of the module under various working modes. The experimental results show that the overall efficiency of modules in air-cooled,water-cooled and compound cooling mode is 76.05%,74.51% and 84.83%,respectively. Additionally,the temperature of the heat absorbing plate can be decreased by 19.08,27.58 and 35.16 ℃ when compared to the PV module. In order to further analyze the influence of design parameters on the electrothermal characteristics of the PV/T module,a three-dimensional numerical model is constructed by ANSYS,and the accuracy of the model is verified by the experimental data. The simulation demonstrates that the electrothermal performance of the module can be effectively enhanced through finned structure with double air ducts. Moreover,as the ambient temperature rises（10-40 ℃）,the module’s overall efficiency increases from 61.85% to 80.31%.
