The invention concerns a method for producing a photovoltaic module, comprising:&#x22c5;&#x2014;providing a plurality of bifacial photovoltaic cells each having a short-circuit current ratio (B),&#x22c5;&#x2014;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,&#x22c5;&#x2014;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,&#x22c5;&#x2014;creating an electrical connection of the front face of the first portion with the rear face of the second portion.

A method of selective formation of silicide on a semiconductor wafer, wherein the metal layer is deposited over the entire wafer prior to application of the SiProt mask such that any etching of the mask does not cause any surface deterioration of the silicon wafer.

The invention relates to a reflective device for a photovoltaic module formed by a plurality of bifacial photovoltaic cells or rows of said cells spaced apart from one another, each cell having an active front face and an active rear face that can capture photons from incident light rays falling on the front and rear faces. The device comprises at least one reflective module to be placed under the cells substantially in line with the gap(s) separating two adjacent cells or two rows of adjacent cells. The reflective module comprises: a first portion, of which the surfaces that are oriented towards the gap have a first curvature such as to send all or part of the incident photons towards the rear face of the cells; and a second portion mounted on the first portion, of which the surfaces oriented towards the gap have a second curvature such as to send all or part of the incident photons towards the rear face of the cells, the second curvature being different from the first curvature.
