Abstract
A photovoltaic cell includes an absorbing layer configured to generate electron-hole pairs from incident photons of incoming light; and a first grating layer arranged at a first surface of the absorbing layer which is opposite to a second surface of the absorbing layer from which light is incident, wherein the first grating layer includes at least one grating extending along the first surface, wherein the at least one grating has grating structures which are dimensioned to provide a reflectivity for light incident through the absorbing layer back into the absorbing layer.
