Abstract: The device presented in this patent application is a solid state “thermoelectric device”, which receives energy from an external heat source by direct contact or by radiation (input), and uses part of that thermal energy to generate electrical energy by radiation (output). This can be used to compose a thermoelectric generator, and/or as a “thermo electronic regulator” in an electronic circuit. Transducers with the same structure and that operate in a similar way, that is, they receive energy from an external source of electromagnetic radiation, or by direct contact with a heat source and transform it by radiation into electrical energy, they are the elements that make up the photovoltaic cells (photoelectric effect) and thermionic generators (thermionic effect).
