摘　　要：为提高太阳电池电效率同时获取可利用的热能,设计制作了槽式聚光太阳能热电联供系统并进行系统测试实验.结果表明:聚光后太阳电池阵列系统热效率随温度升高而线性下降;电池阵列峰值功率点随温度升高左移,电池特性参数FF,Pm,eη和温度影响系数由聚光前的0.735,117.4 W/m2,12.3%和-0.2 W/(m2.℃)分别下降到0.39,550 W/m2,6.9%和-5.1 W/(m2.℃).研究工作对提高槽式聚光系统效率和大规模利用聚光光伏发电提供依据,为后续工作提供参考价值.Abstract： In order to improve the electric efficiency of solar cell ar trough concentrating combined solar Photovoltaic/Thermal system was conducted. The results showed that in concentrating the light, rays and obtain a was designed an the thermal effic vailable heat energy, a d tile performance test iency of the system de- creased linearly with increasing temperature of the cell arrays. At the same time, the maximum output power point of the solar cell arrays moved left and the characteristic parameters of FF, Pm,ηe and temperature coefficient of the cell arrays dropped from 0. 735, 117.4 W/m^2 , 12.3%and -0.2 W/（m2 · ℃） before light concentration to 0. 39, 550 W/m^2 , 6.9% and -5.1 W/（m^2 · ℃）, respectively, after light concentration.
