Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
IN A THERMO-PHOTOVOLTAIC CONVERTER WHEREIN A SOURCE EMITS RADIANT ENERGY OVER A BROAD WAVELENGTH RANGE, A PHOTOVOLTAIC CELL TO PRODUCE ELECTRICAL ENERGY WHEN IRRADIATED BY ENERGY OF A PREDETERMINED WAVELENGTH WITHIN THE RANGE, THE CELL HAVING FRONT AND REAR SURFACES AND BEING SPACED FROM THE SOURCE TO RECEIVE RADIANT ENERGY BEING EMITTED THEREFROM, MEANS ADJACENT THE REAR SURFACE OF THE CELL TO REFLECT BACK TO THE SOURCE RADIANT ENERGY OF A WAVELENGTH LONGER THAN THE PREDETERMINED WAVELENGTH, MEANS ADJACENT THE FRONT SURFACE OF THE CELL TO REFLECT BACK TO THE SOURCE RADIANT ENERGY OF A WAVELENGTH SHORTER THAN THE PREDETERMINED WAVELENGTH, SAID FRONT SURFACE BEING DISPOSED TOWARD THE SOURCE SUCH THAT THE SHORTER WAVELENGTH ENERGY DOES NOT PENETRATE THE CELL AND THE LONGER WAVELENGTH ENERGY DOES PENETRATE THE CELL BEFORE BEING REFLECTED.
Claim 2
Dependent Claim
132 words
IN A THERMO-PHOTOVOLTAIC CONVERTER WHEREIN A SOURCE EMITS RADIANT ENERGY OVER A BROAD WAVELENGTH RANGE, A PHOTOVOLTAIC CELL TO PRODUCE ELECTRICAL ENERGY WHEN IRRADIATED BY ENERGY OF A PREDETERMINED WAVELENGTH WITHIN THE RANGE, THE CELL HAVING FRONT AND REAR SURFACES AND BEING SPACED FROM THE SOURCE TO RECEIVE RADIANT ENERGY BEING EMITTED THEREFROM, MEANS ADJACENT THE REAR SURFACE OF THE CELL TO REFLECT BACK TO THE SOURCE RADIANT ENERGY OF A WAVELENGTH LONGER THAN THE PREDETERMINED WAVELENGTH, MEANS ADJACENT THE FRONT SURFACE OF THE CELL TO REFLECT BACK TO THE SOURCE RADIANT ENERGY OF A WAVELENGTH SHORTER THAN THE PREDETERMINED WAVELENGTH, SAID FRONT SURFACE BEING DISPOSED TOWARD THE SOURCE SUCH THAT THE SHORTER WAVELENGTH ENERGY DOES NOT PENETRATE THE CELL AND THE LONGER WAVELENGTH ENERGY DOES PENETRATE THE CELL BEFORE BEING REFLECTED.
Claim 3
Dependent Claim
116 words
IN A THERMO-PHOTOVOLTAIC CONVERTER INCLUDING A SOURCE OF RADIANT ENERGY WHICH EMITS OVER A BROAD SPECTRUM OF WAVELENGTHS, A PHOTOVOLTAIC CELL TO PRODUCE AN ELECTRICAL OUTPUT WHEN IRRADIATED BY ENERGY OF A PREDETERMINED RANGE OF WAVELENGTHS WITHIN THE RANGE, THE CELL HAVING A FRONT SURFACE FACING THE SOURCE AND A REAR SURFACE DISPOSED AWAY FROM THE SOURCE, ELECTRODE MEANS ADJACENT THE REAR SURFACE OF THE CELL AND ADAPTED FOR ELECTRICAL CONNECTION TO AN OUTPUT LINE, THE ELECTRODE MEANS HAVING SPACES FORMED IN THE SURFACE ADJACENT THE CELL, SAID SPACES CONTAINING A SELECTED SUBSTANCE WHICH, IN COMBINATION WITH THE MATERIAL OF THE ELECTRODE, IS REFLECTIVE TO RADIANT ENERGY OF A WAVELENGTH LONGER THAN THE PREDETERMINED WAVELENGTH RANGE.
Claim 4
