Light-reflecting grating structure for photovoltaic devices

International Business Machines Corporation, Egypt Nanotechnology Center (2018) Light-reflecting grating structure for photovoltaic devices. .

Abstract

A photovoltaic cell includes an absorbing layer configured to generate electron - hole pairs from incident photons of incom ing 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 reflec tivity for light incident through the absorbing layer back into the absorbing layer.
