Abstract
For the present invention, a P-type thermo-electric thin-film layer and a N-type thermo-electric thin-film layer are respectively deposited on two sides of an insulating substrate. During the deposition, the P-type thermo-electric thin-film layer and the N-type thermo-electric thin-film layer are deposited and connected on the same exposed side of the insulating substrate, and then a PN junction is formed. This method makes the fabrication simplified without special process for connecting the P-type thermo-electric thin-film layer and the N-type thermo-electric thin-film layer. Due to the features of thin-film thermo-electric material, the performance of thermo-electric generator is improved. During the deposition, the P-type thermo-electric thin-film layer and the N-type thermo-electric thin-film layer are deposited and connected on the exposed side of the insulating substrate, so welding is not required in this heating surface side. The performance of thermo-electric generator fabricated in heating surface working temperature is accordingly greatly improved.
