摘　　要：建立了太阳能PV/T(Photovoltaic/Thermal)系统的热电模型,编制了Matlab程序,采用迭代法对电热参数进行耦合求解。研究了PV/T系统在呼和浩特不同季节下的热电效率,电池温度和性能曲线的变化,通过与实验数据对比,验证了该模型具有较高的精度。实验结果显示了环境温度、风速、入射辐射量对太阳能PV/T系统热、电以及综合性能的影响:PV/T系统夏季的日平均电效率、热效率及正午组件最大功率分别为14.1%、34.5%和180.8 W,冬季的日平均电效率、热效率及正午组件最大功率分别为16.1%、24.8%和190.3 W。Thermal and electrical models of solar PV/T system are proposed and their MATLAB programs are developed which can solve thermal and electrical parameters by using the iteration method and coupled method. The variation of thermal and electrical efficiency, temperature of solar cell and the performance curve of PV/T system are simulated by the MATLAB program in different seasons in Hohhot when the ambient temperature, wind speed and direct solar radiation change. Comparing with the experiment data, the simulation results show the MATLAB program has high accuracy. Daily mean electric and thermal efficiency and noon max power of PV/T system in summer day are 14.1%,34.5%,180 W, while those are 16.1%,24.8%,190.3 W in winter.
