Article Preview

In order to improve electric efficiency of solar cell arrays and obtain available heat energy, the solar trough concentration photovoltaic/thermal system has been constructed and the experiment performance and analysis of solar cell arrays have been carried out. The results show that in concentration the thermal efficiency of system linearly decreases with the temperature of cell arrays increasing. In non-concentration, the maximum power output (Pm) temperature coefficients of single crystalline silicon solar cell, polycrystalline silicon cell array and super cell array are -0.2 W/(m2·°C), -0.15 W/(m2·°C) and -0.16 W/(m2·°C), respectively. In concentration, the Pm temperature coefficients are -11.8 W/(m2·°C), -5.9 W/(m2·°C) and -5.1 W/(m2·°C).
