摘　　要：利用所设计的2m^2槽式聚光热电联供系统,对晶硅阵列和砷化镓电池阵列进行性能测试实验,结果表明:砷化镓电池阵列的聚光特性优于晶硅电池阵列。优选出一定聚光比作用下性能较好的砷化镓电池阵列建立10m^2槽式太阳能聚光热电系统,实验表明:10m^2系统的电池阵列电效率为23.21%,系统光电效率和光热效率分别为9.88%和49.84%,系统(?)效率为13.48%,比基于槽式聚光加热真空管系统(?)效率高158%,比平板光伏发电系统(?)效率高16%。对采用空间太阳电池阵列的10m^2聚光热电系统性能分析表明,槽式聚光热电联供系统发电成本已与平板的持平,且每年还可提供4838.38MJ热量供用户使用。The performance testing experiment of crystalline silicon cell array and GaAs cell array have been carried out on the 2m^2 trough concentrating photovoltaic/thermal system independently. Experimental results showed that performance of GaAs cell array is better than that of crystalline silicon celt array. The 10m^2 trough concentrating solar photovoltaic/thermal system which adopt GaAs cell array selected form prior experimental result of excellent performance in condition of solar concentrating radiation has been established. The experimental results showed that photoelectric efficiency of GaAs cell array is 23.21%, the electric efficiency and thermal efficiency of this system are 9.88% and 49.84%, respectively at the 10m^2 trough concentrating system. The exergy of the system is 13.48%, which is higher 158% than that of evacuated tube heated by trough concentrating and is higher 16% than flat-plate photovoltaic system. The cost of generate electricity with trough concentrating photovohaic/thermal system adopted super cell array can catch that of standard flat-plate photovohaic station, in addition, the photovoltaic/thermal system can offer 4838.38MJ heat energy to user every year.
