SEMI-TRANSPARENT THIN-FILM PHOTOVOLTAIC MONO CELL

摘要

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.

1. A photovoltaic mono cell semi-transparent to light, comprising:
a plurality of photovoltaic active zones separated by transparency zones, said photovoltaic active zones being formed of a stack of thin films comprising a transparent electrode, an absorber film and a metallic electrode which are arranged on a substrate transparent to light; and said transparency zones being apertures made at least in the metallic electrode and in the absorber film to allow through a maximum of light; and an electrically conducting collection gate arranged either in contact with the transparent electrode to reduce its electrical resistance or in contact with the absorber to facilitate the collection of the electric current generated by said mono cell.
