What is a solar thermoelectric generator?
Solar thermoelectric generators (STGs or STEGs) have been the research focus of thermoelectric technology in recent years. The TE phenomenon was discovered in the eighteenth century, it generated a rather small voltage between two dissimilar metals, and it was mostly used as thermocouples.
What is thermoelectric power generation (TEG)?
Thermoelectric power generation (TEG) is the most effective process that can create electrical current from a thermal gradient directly, based on the Seebeck effect. Solar energy as renewable energy can provide the thermal energy to produce the temperature difference between the hot and cold sides of the thermoelectric device.
How does a converging thermoelectric generator work?
The computational simulation suggested that the converging thermoelectric generator system generates a higher output power, induces a lower backpressure power loss, and has a more uniform temperature distribution than the conventional structure.
Are solar thermoelectric generators a good alternative to fossil fuels?
Solar energy, known as a free, reliable, and inexhaustible source of clean energy, is regarded as one of the most promising solutions to reduce the consumption of fossil fuels and improve environmental issues.
