Patent ID: 8859885

Claim:
A method for manufacturing a photovoltaic device comprising n photovoltaic cells, all n photovoltaic cells of equal length and width, wherein each photovoltaic cell comprises: two current output terminals, at least one photovoltaic junction, current collecting buses, and connecting strips that extend from the current-collecting buses to the current output terminals; the method further comprising steps of stacking: a front photovoltaic cell 1 having a first surface corresponding to an upper face of the photovoltaic device, an apertured lamination interlayer having apertures facing the current output terminals of the front photovoltaic cell 1, on which the lamination interlayer is deposited, at least one intermediate photovoltaic cell i (1<i<n), each intermediate photovoltaic cell i comprising 2(i−1) apertures allowing the current output terminals of the photovoltaic cells 1 to (i−1) to be fitted into plugs of a junction box and optionally two apertures allowing the current output terminals of the photovoltaic cell i to be fitted into plugs of the junction box, an apertured lamination interlayer below every intermediate cell I having apertures facing the current output terminals of the photovoltaic cell i, on which the lamination interlayer is deposited, a back photovoltaic cell n having a surface corresponding to the lower face of the photovoltaic device comprising 2(n−1) apertures allowing the current output terminals of the photovoltaic cells 1 to (n−1) to be fitted into plugs of the junction box and optionally two additional apertures allowing the current output terminals of the photovoltaic cell n to be fitted into plugs of the junction box, and laminating the stack, such that the stack of n photovoltaic cells has a parallelepiped shape, the lamination either being obtained by sequential operations after each cell or interlayer has been deposited, or being obtained in a single step after the cells and the interlayers have been assembled, wherein the current output terminals are placed on either the lower face or the upper face of the multijunction photovoltaic device.
