Abstract
A photovoltaic module includes at least two photovoltaic cells in series, each rectangular cell including, respectively, a first rear thin film electrode, a photovoltaic stack having at least two active materials included between the rear electrode and a transparent conductive electrode made of a thin film, the electrode TC being capable of collecting and transmitting an electric current generated by the photovoltaic stack, the two photovoltaic cells being electrically connected in series by an electrical contact strip that is included between the electrode TC of the first cell and the rear electrode of the second cell. The local thickness of the electrode TC of the cell varies as a function of the distance to the electrical contact strip. Also described are methods for depositing and etching the transparent conductive film so as to simultaneously manufacture a plurality of cells for a single module.
