Abstract
Fabrication of a double-sided photovoltaic cell, with two opposite active surfaces, comprising a step of depositing, on each active surface, at least one electric contact. The deposition step comprises in particular a shared operation of depositing on each of the active surfaces, implemented by electrolysis in a shared electrolysis tank comprising: a first compartment for depositing a metal layer on a first active surface of the cell, for fabrication of a contact comprising said metal layer on the first active surface; and a second compartment for depositing, by oxidation, a metal oxide conductor layer on the second active surface of the cell, for the fabrication of a contact comprising said metal oxide layer on the second active surface.
