摘　　要：以效率和能量效率作为判据,通过实验和数值模拟的手段,研究高、低电池覆盖率工况对PV/T系统光电光热性能的影响,主要分析在各种系统参数变化的情况下,高、低电池覆盖率工况对PV/T系统综合性能的影响。结果表明:电池覆盖率对系统光电性能影响较大,对光热性能影响较小。总体上系统能量效率在高、低电池覆盖率工况下变化一致;而对系统效率的影响因高、低电池覆盖率工况的不同而不同。In this paper, using exergetic and energetic efficiency as criterion, by means of experiments and numerical simulation , the performance of PV/T system has been studied in the conditions of high and low coverage of cells, and the affect of overall performance of PV/T system with high and low rate of cell coverage has been analyzed under the conditions of the variation of system＇ s parameters. The results show that cell coverage greater impact on the system performance of photovoltaic, smaller on the thermal performance. The energy efficiency changes consistently in the condition of high and low rate of cell coverage, but the affect of exergetic efficiency is different with the condition of high or rate of cell coverage.
