Flexible thermoelectric generators with inkjet-printed bismuth telluride nanowires and liquid metal contacts

Abstract

A nanowire based flexible thermoelectric generator with liquid metal contacts is fabricated by inkjet and spray printing.

High-performance thermoelectric silver selenide thin films cation exchanged from a copper selenide template

“…15 Many nanostructured TEs have been prepared via solution processing on exible substrates with adaptable form factors that allow integration of these TE devices into a variety of applications that would otherwise be inaccessible. [16][17][18] If exible TE devices can be fabricated on fabrics, it would have implications in enabling temperatureregulating clothing that can reduce the energy and space consumption of household and building HVAC systems signicantly.…”

Influence of the thermal annealing on the morphological and structural properties of ZnO films deposited onto polyimide substrates by ink-jet printing

“…2D printing is a fast (for example, ordinary office printer allows to deposit 1 m 2 coating only for 20 min) and zero waste which opens the way to obtain coatings onto flexible substrates with predefined sizes [1][2][3]. The flexible solar cells, thermoelectric generators, sensors, among others, have already been developed by applying the 2D printing technique [4][5][6]. For such devices, that is important to obtain high-quality functional elements, for instance, buffer and window films for solar cells; n-type leg for thermoelectric generators; sensitive elements for sensors.…”

Recent advances, design guidelines, and prospects of flexible organic/inorganic thermoelectric composites

“…After annealing at 450 1C, maximum power factors of 180 mW (m K 2 ) À1 and 110 mW (m K 2 ) À1 were obtained for the Bi 2 Te 3 and Bi 0.5 Sb 1.5 Te 3 films. 103 The power of the generator could reach B130 nW at DT = 32 1C, and it maintained its performance even after 50 bending experiments (with a tight radius of curvature of B10 mm), as shown in Fig. 8.…”
