N-type PbSe-based thermoelectric material and preparation method and application thereof
The invention discloses an n-type PbSe-based thermoelectric material. The chemical formula of the n-type PbSe-based thermoelectric material is Pb < 0.8 + x > Ag < 0.1 > Sb < 0.1 > Se < 0.8 > Te < 0.2 >, wherein the value range of x is from 0.01 to 0.20; x represents the mole fraction of the doped Pb; pbSe is converted from p-n before doping to a doped n-type material, the conductivity is effectively improved, the power factor PF is greatly improved in the whole temperature range, and finally the thermoelectric figure of merit is improved.
本申请公开了一种n型PbSe基热电材料，所述n型PbSe基热电材料化学式为Pb0.8+xAg0.1Sb0.1Se0.8Te0.2；其中，x的取值范围为0.01～0.20；x表示掺杂的Pb的摩尔分数；实现了PbSe由未掺杂前的p‑n转变，到掺杂后的n型材料，有效提高了电导率，功率因子PF在整个温度范围内都有大幅度提升，最终实现热电优值的提升。
