Abstract

The invention concerns a method for producing a photovoltaic module, comprising:⋅—providing a plurality of bifacial photovoltaic cells each having a short-circuit current ratio (B),⋅—asymmetrically cutting each cell into two portions, such that the ratio between the surface areas of said portions is substantially equal to the short-circuit current ratio (B) of said cell or to the average short-circuit ratio of the set of cells,⋅—juxtapositioning said cell portions in a main plane of the module in order to form pairs of cell portions chosen such that the front face of the first portion has a short-circuit current substantially equal to the short-circuit current of the rear face of the second portion, said portions being arranged such that the front face of the first portion and the rear face of the second portion coincide with the front face of the module,⋅—creating an electrical connection of the front face of the first portion with the rear face of the second portion.
