A photovoltaic device is provided that comprises a photovoltaic active zone being formed of a stack of thin films comprising a first electrode, an absorber film and a metallic electrode. A collection gate is arranged in contact with the first electrode to reduce its electrical resistance and avoid direct physical or electrical contact with the metallic electrode. The photovoltaic active zone includes a plurality of channels, made in the metallic electrode and the absorber film. The collection gate is separated from the metallic electrode and from the absorber film by a dielectric material.

Thin-film photovoltaic cell

The invention relates to a photovoltaic mono cell that is semi-transparent to light, comprising a plurality of active photovoltaic zones that are separated by transparent zones, said active photovoltaic zones being formed from a stack of thin films arranged on a substrate that is transparent to light, said stack of thin films consisting at least of a transparent electrode, an absorber layer and a metal electrode, said transparent zones being apertures produced at least in the metal electrode and in the absorber layer in order to allow as much light as possible to pass, characterized in that it furthermore comprises an electrically conductive collecting gate arranged either making contact with the front electrode in order to decrease the electrical resistance of the transparent electrode, or making contact with the absorber in order to facilitate collection of the electrical current generated by said mono cell.
