Achieving high thermoelectric conversion efficiency in Bi2Te3-based stepwise legs through bandgap tuning and chemical potential engineering

“…7,8 The main construction unit of the TE modules is thermoelectric unicouples, which consist of serially connected n-and p-type semiconductor materials with exceptional properties. 9 Particularly, low lattice thermal conductivity κ L , high carrier mobility µ, narrow bandgap E g (but not lower than 8 k B T, where k B is the Boltzmann constant and T is the temperature), high solubility of dopants, and high mechanical strength are the main requirements for thermoelectric materials, which can be used for the fabrication of the TE converters. [10][11][12] To date, many attempts have been accumulated to enhance the ZT parameter (ZT = S 2 σT/κ, where S is the Seebeck coefficient, and σ and κ are the electrical and thermal conductivity, respectively) of materials.…”

Optimization of Waterblock Cooling Water Flow Rate in a Thermoelectric Generator Charcoal Furnace

“…Solidfuel stoves, such as wood-fueled stoves, can be connected to a micro-scale power plant, which is realized using a thermoelectric generator [9]. In an electric device called a TEG generator, heat (or temperature differential) is converted directly into electrical energy [10]. Seebeck originally identified the thermoelectric phenomenon in 1822 after seeing the flow of electricity when there is a temperature differential between two objects, with two dissimilar metals combined in one wild place while the other temperature difference is stored at a lower temperature [11,12].…”

Effect of the crystal structure and chemical bonding on the electronic and thermal transport in Cu2MeHf3S8 (Me – Mn, Fe, Co, Ni) thiospinels

“…Development of the new materials with ultralow thermal conductivity for thermoelectrics and thermal barrier coatings is among the hot topics in modern materials science [1][2][3][4]. However, materials with low thermal conductivity usually contain heavy and hazardous elements [5][6][7][8], which is in contradiction with the required low weight of thermoelectric devices [9,10] and even more crucial for the thermal barrier coatings used for the protection of aircraft turbines [4]. However, a lot of recent works show that ultralow thermal conductivity can be achieved even in materials consisting of lightweight elements through the crystal structure complexity engineering and chemical bonding hierarchy [3,[11][12][13][14][15].…”
