Solar Panel Thermoelectric Generator

One of the emerging energy technologies is thermoelectric generators tegs due to the capability of converting direct thermal energy to electricity and silent operation since they have not any.

Thermoelectric generators or tegs are very similar to photoelectric generators which we now call photovoltaic generators or solar pvcells. A thermoelectric generator can be made using bimetallic materials but the result often is bulky and expensive. A photovoltaic generator converts light directly into electricity and a thermoelectric generator converts heat directly into electricity. The conversion of sunlight into electricity has been dominated by photovoltaic and solar thermal power generation.

The efficiency is 7 8 times higher than the previously reported best value for a flat panel. Unlike pv panels steg uses heat instead of. Manufactured using a process much like photocells they are expensive and hard to cool.

In 1821 thomas johann seebeck discovered the thermoelectric effect which is the generation of electric current from heat. The developed solar thermoelectric generators stegs achieved a peak efficiency of 4 6 under am1 5g 1 kw m2 conditions. Thermoelectric generators or tegs are very similar to photoelectric generators which we now call photovoltaic generators or solar pv cells. The national renewable energy laboratory nrel is developing a solar thermoelectric generator to directly convert heat from concentrated sunlight to electricity.

Current research is focused on solid state devices that use doped semiconductors made from bismuth or lead telluride or calcium manganese oxide. In this video the upcoming the upcoming technology of solar thermo electric generators steg has been explored. Solar thermoelectric power generator.
