太阳电池光伏光热一体化系统的性能研究

Performance study of a solar hybrid photovoltaic and thermal system

为了提高太阳能的综合利用效率,同时获取电能和热能,将铜管换热器加装在太阳电池板背,构成太阳电池光伏光热(PV/T)一体化系统。采取对比实验法在呼和浩特地区对太阳电池板进行光伏光热性能测试。实验结果表明,在相同的太阳辐照度和环境温度条件下,装有铜管换热器的单块太阳电池的输出功率比普通单块太阳电池实际输出功率提高近17%。

In order to improve the solar energy efficiency and to acquire electricity and hot energy, a copper exchanger was placed on PV rear surface to build a solar hybrid photovoltaic and thermal system （PV/T）. The comparable experiments were performed to demonstrate its performance at Hohhot. The results show that under the same solar radiation and environmental temperature, the output power of the single solar cell with heat exchanger increases almost 15% than the single solar cell.
