“…As clearly defined V 1 is the voltage from the p -type leg at the cold side of the thermoelectric generator, and V 2 is the voltage at the n -type leg on the cold side of the thermoelectric generator. An appreciate the electrical connection of the device with an external load ( R L ) in a closed-loop will run the load by the device due to the thermal gradient created [16]. The pairing of n -type and p -type semiconductors is called a thermocouple.…”

“…The efficiency of TEG can be improved by either enhancing ZT value or by reducing the heat loss or improving heat energy utilization by adjusting the structure [8]. A TE generator can consist of many thermocouples which either can be connected in series to enhance the voltage output or can be connected in parallel to increase the current output [16].…”

Thermoelectric (TE) materials based on conjugated/conductive polymers can directly convert heat into electricity, and thus found promising applications in energy scavenging and cooling technologies. The performance of these thermoelectric materials is governed by different parameters like the nature of the material, thermal stability, electrical conductivity, Seebeck coefficient, and thermal conductivity. Although the traditional inorganic semiconductor materials such as PbTe (Lead Telluride), Bi2Te3 (Bismuth Telluride), SiGe (Silicon-Germanium), SnSe (Tin Selenide), and Skutterudite (CoAs2) are giving high performance, they have some inherent limitations, such as poor processability, toxicity, rare availability, and high cost of manufacturing. Whereas, organic conjugated polymers such as polyacetylene (PA), polyaniline (PANi), Poly(3-hexylthiophene) (P3HT), polypyrrole (PPy), poly 3,4-ethylenedioxythiophene (PEDOT), etc. have low cost of synthesis, light in weight, low toxicity and better processibility. Organic textile thermoelectric generators (T-TEG) can be prepared by in-situ polymerization of the conjugated polymers onto textile substrates. This article reviews the preparation, design and performance of these T-TEGs. Various approaches and scopes of improvement of efficiency of the thermoelectric effect of the T-TEGs are discussed. Various potential applications of the T-TEG in different fields are also described.

“…The global consumption of oil increased from 95 million barrels per day in 2014 to 100 million barrels in 2018 [1]. The cost of electricity has been increasing in recent years due to the limited supply of oil and economic and political factors [2]. Continuation of using fossil fuels will soon reach a critical point from a sustainability point of view [3].…”

Life Cycle Assessment of Thermoelectric Generators (TEGs) in an Automobile Application

In this paper, a possibility to reduce the environmental burdens by employing thermoelectric generators (TEGs) was analyzed with a cradle-to-grave LCA approach. An upscaling technique was newly introduced to assess the environmental impacts of TEGs over its life cycle. In addition to CO2 emissions, other environmental impacts as well as social impacts were assessed using the Life Cycle Impact Assessment Method based on Endpoint Modeling (LIME2). The analysis was conducted under two scenarios, a baseline scenario with a 7.2% conversion efficiency and a technology innovation scenario with that of 17.7% at different production scales. The results showed that while GHG emissions were positive over the life cycle under the baseline scenario, it became negative (−1.56 × 102 kg-CO2 eq/kg) under the technology innovation scenario due to GHG credits in the use phase. An increase in the conversion efficiency of the TEG and a decrease in the amount of stainless steel used in TEG construction are both necessary in order to reduce the environmental impacts associated with TEG manufacture and use. In addition, to accurately assess the benefit of TEG deployment, the lifetime driving distance needs to be analyzed together with the conversion efficiency.

“…This has been possible by analyzing the different electrical connections between the tiles and at different temperatures. These particular studies have been also adopted in a practical application where homes were equipped of TEG tile in order to carry out electrical power from temperature difference, [26,27]. This is the case of Seebeck effect.…”

“…This is the case of Seebeck effect. The system in [26] is characterized aluminum heat sink and a thermo-electric cooler IC (Peltier device) that will be used as a generator. The two sides of the Peltier device are the cold and hot sides that will give the temperature difference which is used to generate electricity.…”

The aim of this paper is to develop an experimental study on the effect of the magnetic field on thermoelectric generators (TEG) that have been used in the past until today according to the Peltier-Seebeck(PS) effect as a bidirectional conversion system of heat and electrical energy. The magnetic field is generated by using a common stator-field(SF) having two pole-shoes expansions shaped in a cylindrical symmetry both winded by two coils connected in series and powered by ac-source. The experimental set-up is performed by using customized jigs manufactured by a 3D printer in order to locate capacitors that allow to carry out magnetic field value coming from the stator field. The magnetic field has been calculated then by using Maxwell’s equations in order to identify the induced voltage on the pn-joints characterizing the TEGs. The calculation of eddy current induced in the pn-joints plays a key role in developing the expression of the voltage coming out of the electrical wires of the TEG tile. The theoretical expression of voltage has been validated experimentally by tuning the integration parameter carried out in the current density expressions. The validation is successful but the most important thing is the usage of TEG tile in an environment where there is a presence of a magnetic field in order to carry out a voltage which has never been done before.
