A method and system for monitoring the quality of photovoltaic cells is described, the method including for each cell: an excitation step, during which the cell to be monitored is subjected to excitation at a predetermined level of excitation; a step of acquiring at least one luminescence image of the cell to be monitored after excitation; and a step of processing the acquired image. The invention is characterized in that, for each cell, there is provided a preliminary step for determining an excitation level adjusted to the cell, the respective adjusted excitation levels of the different cells to be monitored being adapted such that the luminescence intensities of the signals emitted by the different cells are equal at a given reference luminescence intensity.

Method and system for monitoring the quality of photovoltaic cells

A method for producing at least one electric contact by electrochemical deposition of an electrically conducting material on a face of a photovoltaic cell, the contact being formed by first and second lines connected to one another, the second line presenting a larger width than the width of the first line, the method including, before electrochemical deposition, a formation step of at least one area presenting a lower electric conductivity than the electric conductivity of the electrically conducting material, on a part of the face of the photovoltaic cell designed to be electrically connected with the second line, at the level of its intersection with the first line.
