Solid body arrangement for conversion of thermal power into electrical power to produce temperature difference for air conditioning of e.g. home, has emitter located at arrester hot side, and collector layer contacted by another arrester

摘要

The arrangement has an emitter (2) located at a hot side of a metallic conductive arrester (1), and composed of an electride with an electronic work function about 2-2.5 electron volts according to a mayenite-type. The emitter is contacted to a collector layer (3) with a work function about 0.5-1.5 electron volts, where the collector layer is contacted by another metallic conductive arrester. The emitter has thickness about 1-20 mm. The collector layer has thickness about 0.01-10 micrometer. An inert metallic conductive layer (1a) is arranged between the former arrester and the emitter. The collector layer consists of mono sulfides, mono selenide or mono telluride of rare earth metal.
