摘　　要：该文提出了1种半透明光伏窗太阳得热系数(Solar heat gain coefficient,SHGC)的简易室外测试方法。首先通过室外实验研究了不同运行状态下半透明光伏窗的SHGC,实验结果表明,光伏窗开路(Open circuit,OC)状态下的SHGC显著高于最大功率点(Maximum power point,MPP)状态下的SHGC,两者的SHGC差异最高可达11.5%;其次,通过理论分析研究了电池覆盖率对不同运行状态下光伏窗SHGC的影响,同时探究了不同类型光伏窗在上述2种运行状态下的SHGC差异。该文的分析结果将为更准确地评价光伏窗的热工性能和空调负荷计算提供指导,并推动光伏建筑一体化技术发展。A simple outdoor experiment for the solar heat gain coefficient(SHGC)of semitransparent photovoltaic(STPV)windows was proposed in this paper.First,the SHGC of STPV windows under different operating conditions were investigated using outdoor experiments.It was found that the SHGC of STPV windows operating at open-circuit(OC)conditions is significantly higher than that at the maximum power point,and the maximum difference in SHGC between the two can reach up to 11.5%.Then,the influence of solar cells coverage ratio on the SHGC of STPV windows,and the difference of SHGC of various types of STPV windows under the two operating conditions was studied through theoretical analysis.
