“…Figure 5(a) shows the Seebeck coefficient S calculated from ab initio e-ph scattering as a function of carrier concentration n along the c axis direction for n-type KZnP at the temperature (T) from 300 to 1200 K. A negative S means n-type doping, while a positive S represents p-type doping. Obviously, the -S increases with temperature T at the same doping concentration n, and decrease with n at the same T, being consistent with the tendency observed in most of semiconducting thermoelectric materials [4,5]. The -S along c axis direction at n ∼3.2×10 20 cm −3 are in the range of 123.5-195.9 μV K −1 as T increases from 300 to 1200 K. The corresponding thermoelectric parameters along a/b axis direction is available in supporting information.…”

“…Over the past decade, research focus on thermoelectric materials has increased drastically because of their capacity of direct and reversible conversion between thermal and electrical energy via the Seebeck and Peltier effect, which provides a promising route to convert waste heat into electricity [1][2][3][4][5]. The conversion efficiency of thermoelectric materials is limited by the dimensionless figure of merit (zT), defined as…”

Ab initio study on anisotropic thermoelectric transport in ternary pnictide KZnP

Strongly anisotropic bands near the Fermi level via band structure engineering have been proposed to enhance thermoelectric performance in functional materials. Recent works exhibit the presence of flat-and-dispersive-band-like strong anisotropy in a class of ternary transition metal pnictides. Taking KZnP as a representative example, here we investigate the thermoelectric properties of this class of materials based on first-principles calculations and semiclassical Boltzmann transport theory. Strikingly, the calculated lattice thermal conductivity k L shows a strong anisotropy with a small value of about 5.24 (2.58) W m −1 K −1 along the in-plane (out-of-plane) lattice direction at room temperature. Based on the electron relaxation time calculated from intensive ab initio electronphonon interactions, a thermoelectric figure of merit zT of 0.32 is predicted for n-type doped KZnP, about two times lower than the value estimated by the constant relaxation time approximation from deformation potential theory. Nanostructures with the characteristic length shorter than 13 nm can reduce the k L by 40%, enhancing zT to 0.52 along the c axis direction. This work supports that KZnP is a potential candidate for thermoelectric applications.

“…Thermionic converters also need to operate at high emitter temperature (generally above 1000 °C) to yield a higher current density as described by the Richardson–Dushman equation. The radiation spectrum of thermophotovoltaic emitter has to be matched with the bandgap of the photovoltaic cell, which generally requires the emitter temperature to be at least 730 °C (1000 K) for practical power density and conversion efficiency. While thermoelectric devices have been used at room and moderate temperatures for refrigeration and waste heat recovery, there is continued push for high‐efficiency thermoelectric materials at high temperature, such as Si–Ge, half‐Heusler, and oxides, for applications in space exploration, high‐temperature waste heat harvesting (e.g., from industrial furnaces), and combustion‐ or solar‐driven generators 14a…”

High temperature processes are widely used in a variety of existing and emerging industrial and aerospace applications. The thermal properties of high‐temperature materials thus play an important role in controlling the thermal energy, as highlighted by successful applications of thermal barrier coating and aerogels. While thermal transport processes at room and low temperature have witnessed tremendous progress in the past two decades, particularly on the fronts of understanding basic heat transfer properties at the micro‐ and nanoscale, the understanding at high temperature is still at the nascent stage, owing to several unique features at high temperature, such as the dominant Umklapp scattering effect that can render a crystalline material amorphous‐like thermal properties, and the important radiation contribution at high temperature. This lack of systematic understanding, coupled with the challenges in maintaining high‐temperature stability in a large number of materials, has limited the development of materials to meet the thermal transport properties pertaining to several current and emerging high‐temperature applications. This Review is aimed at providing an overview of the basic mechanisms governing thermal transport processes at high temperature, to identify their unique features and challenges, and to explore opportunities in material research for high‐temperature thermal materials.

In this research, due to the present pandemic of COVID-19, we are proposing a stable and fixed semitransparent photo-thermoelectric cell (PTEC) module for green energy harvesting. This module is based on the alloy of Bismuth Telluride Selenide (Bi 2 Te 3 Se), designed in a press tablet form and characterized under solar energy. Here, both aspects of solar energy i.e., light and heat are utilized for both energy production and water heating. The semitransparent PTEC converts heat energy directly to electrical energy due to the gradient of temperature between two electrodes (top and bottom) of thermoelectric cells. The PTEC is 25% transparent, which can be varied according to the necessity of the utilizer. The X-ray diffraction of material and electric characterization of module i.e., open-circuited voltage (V OC ) and Seebeck coefficient were performed. The experimental observations disclose that in the proposed PTEC module with an increment in the average temperature (T Avg ) from 34 to 60 °C, results in the rise of V OC ∼ 2.4 times. However, by modifying the size of heat-absorbing top electrode and by increasing the temperature gradient through the addition of water coolant under the bottom electrode, an uplift in the champion device results in as increment of V OC ∼5.5 times and Seebeck coefficient obtained was −250 μV/ 0 C, respectively. Results show that not only the selection of material but also the external modifications in the device highly effective the power efficiency of the devices. The proposed modules can generate electric power from light and utilize the penetrating sunlight inside the room and for the heating of the water which also acts as a coolant. These semitransparent thermoelectric cells can be built-in within windows and roofs of buildings and can potentially contribute to green energy harvesting, in situations where movement is restricted locally or globally.
