摘要：
A solar parabolic dish photovoltaic (PV)-thermoelectric (TE) power generation system was devised, and its behavior continuously measured under realistic outdoor circumstances. The effect of focal distance was also analyzed. The experimental results showed that the conversion of TE, PV and overall efficiency were 2.96, 16.69 and 19.65%, respectively at the focal distance of 57 cm. The unit obtained its electrical power out from a 2.94 W TE generator and a 1.93 W PV module. The PV module was used to drive a fan for cooling the TE generator and itself. Because of its noiseless operation, light weight, high reliability, and overall environmental friendliness, this concept can be used to solve power supply limitation for low-power wireless sensors.
