Performance evaluation of Bi2Te3-xSex (0.10 ≤ X ≤ 1.80) thermoelectric nanostructured materials

Abstract

ABSTRACT: Traditional materials have a lower commercial impact than thermoelectric (TE) nanostructure materials. These materials have advanced to the point that a thermoelectric generator (TEG) may be built using them. Bi2Te3-xSex (0.10 ≤ X ≤ 1.80) nanostructure materials would overcome the constraint of Bi2Te3 for TEG manufacturing in advanced TE technology. Bi2Te3-xSex (0.10 ≤ X ≤ 1.80) nanostructure materials have recently been recognized as promising TE materials from the research arena for successful use in TEG manufacture. It is already at the commercialization stage and has certain advantages over Bi2Te3. This material's study and development will almost certainly be difficult. The review lays forth a literature strategy for overcoming the constraints of the Bi2Te3 nanostructure material and finding the best composition for TE applications. Furthermore, the performance of existing Bi2Te3-xSex (0.10 ≤ X ≤ 1.80) nanostructured materials is discussed.
