“…In recent years, bismuth telluride Bi 2 Te 3 , with a thermoelectromotive force coefficient of 230 μV/K, and some of its solid solutions with isomorphic compounds, which are used to increase the mobility of electricity carriers and reduce the thermal conductivity of the crystal lattice, have received the most frequent use in the manufacturing of thermoelectric modules. The latter are bismuth selenine Bi 2 Se 3 , with a thermoelectromotive force coefficient of 300 μV/K, and antimony tellurium Sb 2 Te 3 , with a thermoelectromotive force coefficient of 100 μV/K [ 32 , 33 , 34 ]. There are also innovative solutions using PbTe, GeBiTe and Bi 0.5 Sb 1.5 Te 3 [ 35 , 36 , 37 , 38 ].…”

The aim of the work is to develop an energy-saving device that provides the conversion of thermal energy into electrical energy. The design and materials of the thermoelectric converter unit, consisting of 12 thermoelectric converter modules, a cooling radiator and a switching unit, were developed and selected. Based on the test results, the zone of the maximum temperatures in the section of the gas duct recommended for the installation of a gas cooling module using a thermoelectric converter was determined. The technology for cooling gases with the help of a thermoelectric converter was tested on the site located in front of the experimental heat exchanger. An assessment of the efficiency of the conversion of heat into electrical energy was conducted using the design of the thermoelectric converter unit, based on thermoelectric modules TGM 127-1.4-1.2. It was determined that the device is capable of generating electricity stably for production needs. The data obtained showed that, at a temperature difference of 75–80 °C between the wall surface of the gas duct section and the coolant, the power of one thermoelectric converter block of the gas cooling system reaches 9 W.

“…2, Seebeck coefficient becomes anisotropic at high temperatures due to presence of opposite-sign charge carriers. As shown in [11], the negative effect of minority charge carriers is minimized in crystals with the orientation parallel to the axis C. At T > 500 K, it results in higher values of the dimensionless figure of merit ZT for samples with the orientation parallel to this axis [11,14].…”

Due to the increase in energy demand and depletion of natural resources, the development of energy harvesting technologies becomes very important. Thermoelectric devices, based on the direct conversion of heat into electrical energy, are being the essential part of cost-effective, environmental-friendly, and fuel-saving energy sources for power generation, temperature sensors, and thermal management. High reliability and long operation time of thermoelectric energy systems lead to their extensive use in space industry and gas pipe systems. Development and wide application of solar thermoelectric converters (generators) is mainly limited by relatively low thermoelectric conversion efficiency. In this work, we suggest for the first time to use direct conversion of solar energy by systems based on high-performance multistage thermoelectric modules operating in the temperature range of 300 - 900 K for creation of autonomic systems with electric power up to 500 W and electric efficiency up to 15 %. Furthermore, we developed film thermoelectric modules on thin flexible substrates with the figure of merit Z corresponding to that of bulk modules. Such film thermoelectric converters with output voltage of several volts and electric power of several microwatts can be used at micro-solar energy systems.

“…Energy is one of the key factors for a country’s scientific and technological progress and social development [ 1 , 2 , 3 ]. At present, the traditional fossil fuels with limited reserves are still the main source of energy for human beings, but the burning of fossil fuels has caused serious environmental pollution and greenhouse effects [ 4 , 5 , 6 , 7 ]. With the rapid development of global industrialization, environmental pollution and energy shortages are two major problems facing the current world [ 8 , 9 ].…”

Triboelectric nanogenerator (TENG) can convert tiny mechanical energy into precious electrical energy. Constant improvements to the output performance of TENG is not only the driving force for its sustainable development, but also the key to expand its practical applicability in modern smart devices. However, most previous studies were conducted at room temperature, ignoring the influence of temperature on the output performance of TENG. Additionally, due to thermionic emission effect, the electrons transferred to a dielectric surface can be released into a vacuum after contact electrification. Therefore, TENG cannot maintain an effective electrical output under high-temperature conditions. Here, a series of high-temperature operatable flexible TENGs (HO-TENGs) based on nanofiber/microsphere hybrid membranes (FSHMs) was fabricated by electrospinning and electrospraying. The Voc of HO-TENG is 212 V, which is 2.33 times higher than that of control TENG. After 10,000 cycle stability tests, the HO-TENG shows excellent durability. Especially, this HO-TENG can maintain 77% electrical output at 70 °C compared to room temperature, showing excellent high-temperature operability. This study can not only provide a reference for the construction of advanced high-performance TENG, but also provide a certain experimental basis for efficient collection of mechanical energy in high-temperature environment and promote the application of TENG devices in harsh environments.
