Resumen
Conversion of thermal energy by radiant emission with voltaic effect. The invention allows, in contrast to the state of the art, the generation of usable electrical energy by thermally emitting infrared radiation from an emitter-generator, instead of producing energy from the radiation absorbed in a receiver-generator. Thermal energy is obtained from different sources, including solar energy. The temperature difference between the emitter and the background or environment, allows the invention to work under basic thermodynamic principles. Greater control of the flow of thermal energy is achieved through selective surfaces and optical resonators distributed over distances and micrometric scales. The use of flat structures on a substrate simplifies its final application. (Machine-translation by Google Translate, not legally binding)
