Description
This research aimed to design and construct a thermoelectric generator by using solar energy as a heat source, a parabolic dishes having diameter 1.5 m. with a focal length 0.5 m. is used to concentrate the solar radiation. Solar thermal energy is absorbed by a sheet of aluminum on focal zone. The hot side of thermoelectric generator (TEG) device was mounted on an aluminum sheet, heat sink with dimensions 120 x 200 x 50 mm. and cooling fans were installing on the cold side of TEG. Our experiment on 28th and 29th march 2016 at department of physics, faculty of science ubon ratchathani university on the north east of Thailand. Perform collection of the data from 8:30 a.m. to 4:00 p.m. From the result of experiment, at 12:30 on 28th March maximum temperature from solar radiation heat on hot side of TEG is 515.7 K, when intensity of solar energy is 1092 w/m^2 and the maximum power output is 6.28 W.
