Printed Lateral p-n Junction for Thermoelectric Generation.

ABSTRACT: Printed thermoelectric generators (TEGs) show promising potential for converting waste heat into useful electricity at a low cost but fall short of exhibiting a conversion efficiency anticipated from materials' properties. The output power of conventionally printed TEGs in the "π-type" geometry suffers due to low thermal voltage and low current because of high thermal and electrical contact resistance, respectively. Herein, a type of printed p-n junction TEGs (PN-TEGs) as a possible remedy is explored. Two printed PN-TEGs with different thicknesses are fabricated using printed p-type Bi_0.5Sb_1.5Te₃ and n-type Bi₂Te_2.7Se_0.3 materials. The PN-TEGs show a promising way to minimize the influence of thermal and electrical resistan
