The paper established the one-dimension steady models of a trough concentrating photovoltaic/thermal system with a super cell array and a GaAs cell array, respectively, and verified the models by experiments. The gaps between calculation results and experimental results were less than 5%. Utilizing the models, the paper analyzed the influences of the characteristic parameters on the performances of the TCPV/T system with a super cell array and a GaAs cell array, respectively. The reflectivity of the parabolic mirror in the TCPV/T system was an important factor to determine the utilizing efficiency of solar energy. The performances of the TCPV/T system can be optimized by improving the mirror reflectivity and the thermal solar radiation absorptivity of the lighting plate and pursuing a suitable focal line with uniform light intensity distribution. All these works will benefit to the utilization of the trough concentrating system and the combined heat/power supply.
