“…In the marketplace, thermoelectric materials for power generation are available as modules. These devices are usually made of solid-state materials and are composed of multiple layers [43]. Due to their structure, thermoelectric couples are constructed of semiconductor materials (n-type and p-type) connected electrically in a series while thermally connected in parallel.…”

In recent years, the usage potential of alternative energy sources has been gaining importance to increase the efficiency of ships within the scope of the obligations brought by international maritime regulations. The possibility of using alternative energy sources such as solar energy, wind energy, fuel cells, and waste heat recovery technologies on ships has been evaluated in the literature. Today, ships also have waste heat recovery systems as standard equipment for this purpose, and this method is suitable for thermoelectric generators that generate electricity from temperature differences on shipboards. This article aims to review the thermal technologies for the power generation of shipboards. By conducting a case study, an energy efficiency increase was obtained when functional areas were selected on a practical ship, and the effect of this efficiency increase on emissions was examined. As a result of the research, it was discovered that thermoelectric generators increased onboard energy efficiency and have significant potential for sustainability in the maritime sector.

“…The two most "famous" are the Seebeck effect and the Peltier effect. Still, many other thermoelectric effects are associated with the simultaneous application of a field, a magnetic or electric current, such as the Nernst effect, the Thomson effect, or the Ettingshausen effect [1]. The conversion ∆T → ∆V via the Seebeck effect or ∆V → ∆T via the Peltier effect also make it possible to provide applications of these materials in the fields of electricity production or refrigeration.…”

Although thermoelectric technology is little-known in the public domain, it presents an exciting alternative solution in many cases where lost heat energy can be quickly recovered to produce electricity. In the present paper, an attempt is undertaken to exploit this energy. For this purpose, an experimental study is conducted to produce electricity with the thermoelectric effect by utilizing a device placed on a parabolic concentrator. The device is placed on a solar tracker. The results obtained for two days of two distinct months, January and June, revealed that the production in June was higher than that in January by around 92.86%. This distinction is due to the concentrated solar beam being different on a day in each month. A vital product was recorded by utilizing the concentrator. This gadget permitted us to take advantage of the limit of sun-based radiation to produce power. The power may be stored with a legitimate stockpiling procedure.

Two new isostructural compounds with composition of Rb + V 3 + 0.125 V 5 + 0.625 Te 6 + 1.25 O 6 and Cs + V 3 + 0.125 V 5 + 0.625 Te 6 + 1.25 O 6 have been synthesized by solid-state reaction. The crystal structure has been determined by X-ray diffraction analysis using Rietveld refinement. Both compounds possess β-pyrochlore structuretype with cubic space group Fd-3 m (Z = 8); the unit cell parameters: a = 10.04120(27) Å for RbV 0.75 Te 1.25 O 6 Å and a = 10.09119(23) Å for CsV 0.75 Te 1.25 O 6 . The oxidation states of vanadium and tellurium have been confirmed by X-ray photoelectron spectroscopy. The compounds contain vanadium in mixed valence state (3 + and 5 +). The compounds possess the unusual narrow band gap for oxide compounds -in the infrared (IR) range (~0.6 eV). The schematic electronic structure of the compounds has been estimated using XPS, UPS and electronic conductivity data; however, the shifts of the top of the valence edge and the bottom of the conduction band in the water conditions have been calculated using theoretical approximation. The thermal behavior of obtained compounds has been studied by differential thermal analysis. RbV 0.75 Te 1.25 O 6 and CsV 0.75 Te 1.25 O 6 melts at low temperatures (~500 °C) with decomposition and weight loss. The RbV 0.75 Te 1.25 O 6 powder decomposes to amorphous phase, whereas CsV 0.75 Te 1.25 O 6 transform into new β-pyrochlore compound with another composition.
