Description

technical field [0001] The invention relates to a thermoelectric transfer device. Especially about a thermoelectric battery with simple structure, easy manufacture and high thermoelectric conversion efficiency. Background technique [0002] Thermoelectric (TE) devices are electronic devices that convert temperature differences into electrical energy (or vice versa). Recently, attention has been paid to potential applications in the fields of power generation and temperature control. Common thermoelectric devices include thermoelectric generators (TEGs) or thermoelectric coolers (TECs) by exploiting the coupled transport between electrons and phonons. [0003] It is worth noting that important thermoelectric material properties include thermoelectric figure-of-merit (also known as ZT), which is directly related to the conversion efficiency of thermoelectric devices. In order to obtain high-efficiency thermoelectric materials, materials with both high thermal diffusivity an...

Problems solved by technology

However, the conversion efficiency of the physical properties of the p-type and n-type semiconductor solid materials used in the prior art is low, and it is difficult to have specific industrial applications

[0005] In addition, there are previous technologies that combine nano-printed thermoelectric materials and doped semiconductors to make them present electron-rich or electron-poor states, in order to obtain ideal thermoelectric conversion efficiency. However, these two methods themselves have insurmountable problems.

[0006] In particular, one of the advantages of nanoprinting semiconductor structures is the use of promising nanoprinting techniques, however as the printing area requirement increases, the properties of semiconductor structures become increasingly difficult to control

For doping mechanisms, expensive doping elements and harmful doping methods are still used, making them unattractive for most people
