Abstract:
A collective manufacturing method for a plurality of multiple individual electro-optical or photovoltaic cells, each cell including:at least two cavities filled with a liquid and each delimited by a sealing frame arranged between an outer substrate and an intermediate substrate;electrodes arranged on the surface of each substrate turned towards the other substrate;wherein the method includes at least the following steps:(a) providing at least one intermediate plate common to all the cells and in which the intermediate substrate of each cell will be formed, and first and second outer plates which are also common to all the cells and in which the two outer substrates will respectively be formed, the intermediate plate and at least the first or the second outer plate being transparent;(b) forming on faces of the first and second outer plates and the intermediate plate which are intended to face each other a pattern of sets of electrodes, each set of electrodes being associated with an individual cell;(c) depositing on at least one of said faces intended to face each other a sealing material to form a plurality of sealing frames, each sealing frame being associated with an individual cell;(d) forming a zone of least mechanical resistance along a contour of each individual cell in the intermediate plate;(e) combining the intermediate plate with each of the first and second outer plates so that said electrode patterns carried by the first and second outer plates cooperate with the electrode patterns carried by the intermediate plate;(f) bonding the first and second plates to the intermediate plate by means of the sealing material;(g) forming scribe lines delimiting the contour of each individual cell on the outer surface of the first and second outer cells;(h) dividing the batch into individual cells by breaking the first and second outer plates and the intermediate plate along the contour of each cell;(i) filling the cavities of each individual cell with a liquid, the cavities being defined by the first and second plates, the intermediate plate and the sealing frames.
