Patent ID: 7161083

Claim:
A device for producing the flow of electrons due to solar energy being incident thereon comprising: at least one solar cell photovoltaic substrate material; means for determining at least one primary band gap width present in a solar cell substrate material; means for determining at least one primary frequency of light corresponding in energy to said at least one primary band gap width; means for determining at least one harmonic and at least one heterodyne of said at least one primary frequency of light; and at least one means for modifying sunlight positioned between said at least one solar cell photovoltaic substrate material and incident sunlight, whereby said at least one means for modifying sunlight permits limited energies of sunlight from about 300 nanometers to about 1400 nanometers corresponding approximately only to said at least one primary frequency, said at least one harmonic and said at least one heterodyne to pass therethrough, so as to reduce negative interactions within said solar cell photovoltaic substrate material relative to unfiltered incident sunlight.
