摘要：

This paper presents experimental performance results for custom made thermoelectric generator. Two fabrication methods, powder compaction and painting over flexible substrate have been proposed and investigated. Experimental performance results have been presented for thermoelectric cells made from alloying Bismuth (Bi), Tellurium (Te) and Antimony (Sb). Powdered P-type (Bi0.4Sb1.6Te3) and N-type (Bi2Te3) thermoelectric materials were chosen for the construction of the thermoelectric cell. Experimental results showed that P-type Bi0.4Sb1.6Te3 had Seebeck coefficient of 211.77 mu V/degrees C and while N-type Bi2Te3 had a Seebeck coefficient of 109.09 mu V/degrees C. The flexible thermoelectric generator has shown linear increase in open circuit voltage with increase in temperature difference across the cold and hot side. (C) 2017 The Authors.
