英文摘要：

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.
