P-type thermoelectric
WebPbS is a latent substitute of PbTe thermoelectric materials, which is on account of its superiority in low cost and earth abundance. Here, the thermoelectric transport properties of p-type PbS by doping alkali metals (Na and Li) are investigated and it is verified that Li is a more effective dopant than Na.By introducing Li, the electrical and thermal transport … WebGenerally, the thermoelectric module consists of multiple pairs of n- and p-type legs that are connected thermally in parallel and electrically in series ( 4 ). To achieve a high-energy conversion efficiency, high thermoelectric performance for both types of legs is desired.
