Several patents about the use of thermoelectric devices in parallel or cascade configuration with solar cells have been filed. [1] [43] The idea is to increase the efficiency of the combined solar/thermoelectric system to convert solar radiation into useful electricity. Conventional solar cells also suffer from decreased efficiency (-0.45% ...
The use of materials with a high Seebeck coefficient [3] is one of many important factors for the efficient behaviour of thermoelectric generators and thermoelectric coolers. More information about high-performance thermoelectric materials can be found in the Thermoelectric materials article.
The efficiency of a thermoelectric device for electricity generation is given by , defined as =.. The maximum efficiency of a thermoelectric device is typically described in terms of its device figure of merit where the maximum device efficiency is approximately given by [7] = + ¯ + ¯ +, where is the fixed temperature at the hot junction, is the fixed temperature at the surface being cooled ...
The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. [1] A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature ...

Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
where and are the molar weighted segment and area fractional components for the -th molecule in the total system and are defined by the following equation; is a compound parameter of , and . z {\displaystyle z} is the coordination number of the system, but the model is found to be relatively insensitive to its value and is frequently quoted as ...
Thermoelectric power may refer to: Rate of change of the thermoelectromotive force of a thermocouple with temperature Electric power generated from a heat source, such as burning fossil fuel-coal, oil, indirectly through devices like steam turbines
