  • Publication number: 20160043260
    Abstract: Apparatuses and methods are provided for converting solar energy. The apparatus can include an emitter electrode, a collector electrode, a vacuum gap, and an electronic circuit. The emitter electrode can include a first light absorbing layer in direct contact with a first low work function layer. The vacuum gap can be disposed between the emitter and the collector. The vacuum gap can be in direct contact with the first low function layer. The electronic circuit can be coupled to the emitter electrode and the collector electrode. The first low work function layer can be disposed at least partially between the first light absorbing layer and the vacuum gap.

  • Patent number: 8188456
    Abstract: A thermionic electron emitter/collector includes a substrate and a doped diamond electron emitter/collector layer on the substrate. The doped diamond electron emitter/collector layer has at least a first and a second doping concentration as a function of depth such that the first doping concentration is different from the second doping concentration.
