    摘要: An apparatus includes a substrate, at least one type of tuning material, and a composite material. The substrate has an interface surface or material that manifests, in response to light in a color spectrum, a particular color and a first thermal load. The particular color is associated with the first thermal load. The at least one type of tuning material manifests, in response to light in the color spectrum, the particular color and a second thermal load. The particular color is associated with the second thermal load. The first thermal load is different from the second thermal load. The composite material includes the interface surface or material and the at least one type of tuning material. The composite material manifests, in response to light in the color spectrum, the particular color and a tuned thermal load which is different than the first thermal load and the second thermal load.

    摘要: In certain examples, methods, apparatuses and semiconductor-related structures are directed to nighttime-like electrical power generation by use of a spectro-angular selective emitter as an optimal radiative cooler and a thermoelectric power generator (TEG) having a hot side and a cold side. The cold side may be coupled to the spectro-angular selective emitter which is directed to or facing an atmosphere characterized by an absence of solar light. Power may be generated via the TEG based on energy directed from the spectro-angular selective emitter and by controlling or limiting ability of the spectro-angular selective emitter to absorb heat power at frequencies and/or angles where emission of the atmosphere is dominant.
