Abstract: A photovoltaic cell comprising a plurality of film layers, at least one of the layers being a semiconductor film of amorphous, hydrogenated carbon. The preferred embodiment comprises a plurality of semiconductor films sandwiched together in layers, every three layers forming a PIN junction. All films are made of amorphous, hydrogenated carbon and vary only by dopant levels within each PIN junction. There are variations in bandgap from one PIN junction to the next in order that the photovoltaic effect in each PIN junction will be caused by a different portion of the spectrum of light.
