چکیده
Sticky thermoelectric (TE) materials have been inversely designed to enable the mass production of flexible TE sheets through lamination or roll-to-roll processes without using electrically conductive adhesives. They also demonstrated as inorganic/organic hybrid consisting inorganic particles and low-volatilizable organic solvents exhibit Seebeck coefficients based on low thermal conductivities matrix. To achieve energy harvesting 250 µW for driving various electric devices voltage boosters, herein, we employ p- n-type Bi2Te3 due their high coefficients, cover bodies with Au skins because interfacial electrical resistance depends opposing substances at interface. After controlling plating amount skins, a power generation two orders magnitude greater than previous study, i.e., 255 hot plate 110 °C 6 × module. Overall, input from other devices, like light-emitting diodes dye-sensitized solar cells, this study presents hierarchical design that suppresses conduction by hybridizing matrix microscale. This reduces modifying interfaces nanoscale optimizes coefficient atomic scale. compete solid-state modules regards capacity, towards possible further improvement is discussed.

متن کاملFew-quintuple Bi2Te3 nanofilms as potential thermoelectric materials
The thermoelectric transport properties of p-type Bi₂Te₃ nanofilms with various quintuple layers (QL) were systematically investigated based on ab initio electronic structure calculations and Boltzmann transport equations. Our results demonstrated that p-type few-quintuple Bi₂Te₃ nanofilms could exhibit high thermoelectric performance. It was found out that the 1QL Bi₂Te₃ nanofilm had the highe...
متن کاملPorous Thermoelectric Materials
Thermoelectric materials are sometimes prepared using a sintering process in which the achievement of a high density is often one of the objectives. However, it has recently been shown that the introduction of a highly porous material is desirable in synthetic transverse thermoelements. Porosity may also be an advantage in conventional longitudinal thermoelectric modules in which a high thermal...
