This invention relates to a high efficiency device for the direct conversion of light power to electrical power. Present photocells for accomplishing this purpose are well known to the art and have a theoretical efficiency not exceeding about 20%. In practice, realization of efficiency of about 10% has been achieved, but ultimately the theoretical limitation is an upper limit which cannot be exceeded by devices utilizing known construction. The present device differs from the prior art devices in that it utilizes a plurality of dipole antennae for absorbing light photons, employing an alternating electrical field of said photons to cause electrons in the dipole antenna to resonate therewith and absorb electrical power therefrom, with means for rectifying said AC power to DC, said DC being accumulated on conducting busbars from the plurality of antennae and associated rectifying circuits.
In a light/electric energy converter an insulating sheet, a dipole antenna on said sheet to intercept light photons and convert the resolved electric vector of the alternating electromagnetic energy of said photons to an alternating current in said dipole antenna, a first pair of conducting leads connected to the center of said dipole antenna, an alternating current to a direct current rectifier connected to said leads, a second pair of leads from said rectifier, a pair of output terminals connected to a load, said second pair of leads being connected to said terminals to provide DC power to the said load.
