摘要： The invention relates to a photovoltaic module (1) that includes at least two photovoltaic cells (7, 7’) in series, each rectangular cell (7, 7’) including, respectively, a first rear thin film electrode (5, 5’), a photovoltaic stack having at least two active materials (3) included between the rear electrode (5) and a transparent conductive electrode (TC) made of a thin film (4), said electrode TC (4, 4’) being capable of collecting and transmitting an electric current (10, 10’) generated by the photovoltaic stack (3, 3’), the two photovoltaic cells (7, 7’) being electrically connected in series by an electrical contact strip (6) that is included between the electrode TC (4) of the first cell (7) and the rear electrode (5’) of the second cell (7’). According to the invention, the local thickness (e) of the electrode TC (4) of the cell (7) varies depending on the distance to the electrical contact strip (6). The invention also relates to methods for depositing and etching the transparent conductive film (TC) so as to simultaneously manufacture a plurality of cells (7, 7’, 7”…) for a single module (1).
