Abstract
A photovoltaic device configured to substantially avoid radiative recombination of photo-generated carriers, reduce loss of energy of the photo-generated carriers through the phonon emission, extract photo-generated carriers substantially exclusively from the multi-frequency satellite valley(s) of the bandstructure of the used semiconductor material as opposed to the single predetermined extremum of the bandstructure. Methodologies of fabrication and operation of such a device.
