ABSTRACT:
A solar-powered thermionic-photoelectric current generator is disclosed employing a paraboloidal telescope for collecting and concentrating sunlight into a narrow beam which is incident upon a thorium-doped tungsten cathode target within an evacuated envelope, the light being incident on the target at a very large angle of incidence. An anode arranged substantially parallel to the beam of light incident on the cathode target surrounds the major portion of the cathode target and extends an appreciable distance rearwardly from the cathode target. A gas impervious envelope maintains the region of space immediately surrounding the anode and cathode target at a desired vacuum. Electrical conductors leading from the anode and cathode target to points outside the gas impervious envelope can connect the anode and cathode target to an appropriate load. A laser or other similar light amplification means can be included to increase the proportion of light incident about the target which is found in the ultraviolet spectrum.
