Description

technical field [0001] The invention relates to the field of thermoelectric device testing, in particular to a thermoelectric device testing system and method. Background technique [0002] Thermoelectric materials have the Seebeck and Peltier effects, and thermoelectric devices prepared according to these two effects have good application prospects in the fields of power generation and refrigeration. Thermoelectric devices are a kind of non-mechanical solid energy conversion devices. According to their functions, thermoelectric devices are divided into thermoelectric power generation devices and thermoelectric refrigeration devices. When a temperature difference is applied at both ends of the thermoelectric power generation device and the temperature difference is constant, the thermoelectric power generation device can be regarded as a stable current source, which continuously outputs electric energy. Thermoelectric power generation devices can collect the heat emitted fr...
