Abstract:
A method for manufacturing an assembly of individual silicon photovoltaic cells on a metal substrate, and interconnecting a group of cells of said assembly on a support characterised in that it includes the successive steps of:making a metal plate provided with cut out portions delimiting bases of a plurality of non-adjoining individual cells, said cut out portions holding said cells in said plate by points of attachment arranged in a non-adjoining manner or by provisional blocking in said cut out portions; depositing on said plate a stack of silicon layers; depositing on said stack a substantially transparent conductive layer forming a top transparent electrode, sparing at least zones facing the points of attachment and if required, adjacent zones of the cut out portions so as to form a set of individual photovoltaic cells which are electrically separated both from each other and at their top electrodes; removing a group of individual cells from said set; transferring and securing the removed group of cells onto an interconnection support; electrically separating cells of said removed group at said metal plate to form bottom electrodes for these cells; and interconnecting the cells.
