Abstract
The present invention provides a photovoltaic (PV) cell structure for enabling the conversion of incident light to potential electrical energy. The PV cell comprises at least one energy guiding means for converting incident light to potential electrical energy. The energy guiding means includes at least one electron donor and at least one electron acceptor adapted to be linked to a load therebetween. The electron donor is operable to release electrons based on absorption of photons and the electron acceptor may be operable to accelerate photons towards the electron donor and attract electrons released by the electron donor. The electron donor may include at least one photon receptor adapted to have a surface disposed at an angle normal to a range of incident photon angles.
Claims16
A photovoltaic cell characterized by at least one energy guiding means, the energy guiding means including at least one electron donor and at least one electron acceptor, wherein the at least one electron donor is operable to release electrons based on absorption of photons and the at least one electron acceptor is operable to accelerate photons towards the at least one electron donor and attract electrons released by the at least one electron donor, wherein the at least one electron donor and the at least one electron acceptor are adapted to be linked to a load therebetween.
The photovoltaic cell of claim 9, characterized in that the energy guiding means are disposed in consecutively ordered stages such that the energy guiding means operable to convert relatively higher wavelength ranges are disposed nearer the light-exposed surface and the energy guiding means operable to convert the relatively lower wavelength ranges are disposed nearer the substrate.
A photovoltaic cell characterized by at least one energy guiding means, the energy guiding means including at least one electron donor and at least one electron acceptor, wherein the at least one electron donor includes at least one photon receptor adapted to have a surface disposed at an angle normal to a range of incident photon angles, the at least one photon receptor releasing electrons based on photons striking the surface, and the at least one electron acceptor is operable to attract electrons released by the at least one electron donor, wherein the at least one electron donor and the at least one electron acceptor are adapted to be linked to a load therebetween.
