Study on Power Device Using Solar Collector

The thermoelectric generator using solar heat was applied to the device (heat-electricity conversion device) to produce small-scale electricity. The purpose of this study was to investigate the characteristics and performance of the device, which equipped with heat pipe as heat source. The experimental results showed that efficiency of circular single evacuated solar collector was higher 2.7 times than that of rectangular solar collector. Furthermore maximum power of 5 watt was obtained when 2 devices with series array were used and it could be more improved by increasing the number of device or measurement time.
