Thermoelectric Coolers as Alternative Transducers for Solar Energy Harvesting

This paper features experimental results about Thermoelectric Coolers (TECs) employed as Thermoelectric Generators (TEGs) for a low temperature application based on solar thermal Energy Harvesting. Design considerations are discussed and a constructed testing device for parallel evaluation of three TEC modules is described. Results show that with relatively low temperature gradients, enough power is generated for Energy Harvesting applications.
