Description

technical field [0001] The invention relates to a thermoelectric conversion material, in particular to a flexible thermoelectric conversion material. Background technique [0002] The thermoelectric effect (Thermoelectric Effect) means that when the temperature at both ends of the object is different (there is a temperature gradient inside the object), the carriers in the object will diffuse from the high temperature area to the low temperature area along the temperature gradient, resulting in the number of carriers in the low temperature area Gradually more than the high temperature region, thereby establishing a built-in electric field. The built-in electric field will force the carriers to perform a drift movement opposite to the diffusion movement, and finally the drift movement and the diffusion movement will balance, so that a constant potential difference exists at both ends of the object. The main parameter to measure the thermoelectric effect is Seebeck coefficient...

Problems solved by technology

However, when it is actually applied to thermoelectric conversion materials, the thermoelectric conversion efficiency of thermoelectric conversion materials based on conductive polymers needs to be further improved.
