ABSTRACT:The present work highlights the progress in the field of flexible thermoelectric generator (f-TEGs) fabricated by 3-D printing strategy on the typing paper substrate. In this study, printable thermoelectric paste was developed. The dimension of each planer thermoelectric element is 30mm*4mm with a thickness of 50 μm for P-type Bismuth Tellurium (Bi2Te3)-based/ poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) leg. A single thermoleg with this dimension can generate a voltage of 5.38 mV at a temperature difference of 70 K. The calculated Seebeck Coefficient of a single thermoleg is 76.86 μV/K. This work demonstrates that low-cost printing technology is promising for the fabrication of f-TEGs.

N-type Bi2Te3 and p-type Sb2Te3 thermoelectric thin films have been prepared by RF and DC co-sputtering. The Seebeck coefficient of n-type Bi2Te3 and p-type Sb2Te3 thin films is about -122 μVK-1 and 108 μVK-1, the power factor is about 0.82×10-3 Wm-1K-2 and 1.60×10-3 Wm-1K-2. Then, the films have been selected to fabricate the thin film thermoelectric generator. The results show that the open-circuit voltage of 12.2 mV and the output power of 3.32 μW are obtained for a thin film generator with the temperature difference at 60 K.

Releasing Process

This paper presents a new way to design a low-cost micro-thermoelectric generator (μ-TEG) which can be fabricated by using electrochemical and MEMS technology. The overall dimension of the μ-TEG is about 13mm × 13mm × 0.4mm, which contains 128 p- and n-type pairs of semiconductors connected electrically in series and thermally in parallel. The p-type antimony telluride (Sb2Te3) and n-type bismuth telluride (Bi2Te3) with an optimal thickness of 20μm were designed to deposit in a flexible polymer mold formed by photolithographic patterning of Polyimide (PI) with a three electrode configuration. Simulations of the thermocouple with PI mold were carried on, using finite element analysis. The analysis shows the possibility to achieve 3.5 mV while the difference in temperature is 10K and the thickness of the silicon substrate is 400μm, which reveals that the output power of the thermocouple without releasing process is only 4% lower than the one with the releasing process. Therefore the PI mold is not removed, considering the potential for easier fabrication and lower cost. The deposition parameters were also studied and optimized for the best thermoelectric performance. In our experiments, the n- and p-type semiconductors could be obtained when the voltage and current are around 50mV versus saturated calomel electrode (SCE) and 40 mA, respectively.

Remarkable Progress

Carbon nanotubes (CNTs) have attracted much attention in developing high-performance, low-cost, flexible thermoelectric (TE) materials because of their great electrical and mechanical properties. Theory predicts that one-dimensional semiconductors have natural advantages in TE fields. During the past few decades, remarkable progress has been achieved in both theory and experiments. What is more important is that CNTs have shown desirable features for either n-type or p-type TE properties through specific strategies. Up to now, CNT‒polymer hybrids have held the record for TE performance in organic materials, which means they can potentially be used in high-performance TE applications and flexible electronic devices. In this review, we intend to focus on the intrinsic TE properties of both n-type and p-type CNTs and effective TE enhanced strategies. Furthermore, the current trends for developing CNT-based and CNT‒polymer-based high TE performance organic materials are discussed, followed by an overview of the relevant electronic structure‒TE property relationship. Finally, models for evaluating the TE properties are provided and a few representative samples of CNT‒polymer composites with high TE performance are highlighted.

Influence Of Temperature On

In order to achieve the energy recovery of the coolant heat for internal combustion engine (ICE) using the thermoelectric generation (TEG) technology, one test bed for studying the influence of temperature on the characters of thermoelectric generators was established and the relationship between the temperature and characters of thermoelectric generator was researched based on it. The results showed that the cooling effect improved with the increase of fan speed which the fan was installed in the vertical direction of the radiator, but the cooling effect had a limit speed value. And it also indicated that the forced air cooling was better than the natural convection cooling method which can effectively reduce the temperature of the cold end while it has little effect on the hot end temperature. Moreover, the Seebeck coefficient was reduced with the increase of temperature difference between the two ends of thermoelectric generator and the Seebeck coefficient was also declined with one end temperature rise when the other end temperature was constant.
