Abstract
Official abstract text for this publication.
The invention relates to a method for manufacturing a photovoltaic module comprising a plurality of solar cells in a thin-layer structure, in which the following are consecutively formed: an electrode on the rear surface ( 41 ), a photovoltaic layer ( 46 ) obtained by depositing a layer ( 42 ) of precursors and by annealing such as to convert the precursors into a semiconductor material, and another semiconductor layer ( 43 ) in order to create a pn junction with the photovoltaic layer ( 46 ); characterized in that the layer ( 42 ) is deposited in a localized manner, such as to leave free at least one area ( 410 ) of the electrode on the rear surface ( 41 ) placed between two adjacent cells, wherein the annealing step modifies said area ( 410 ) which has higher resistivity than the rest of the electrode on the rear surface ( 41 ), such as to provide electric insulation between two adjacent cells.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for producing a photovoltaic module comprising a plurality of solar cells in a thin-film structure, wherein the process comprises: producing successively: a back-face electrode, a photovoltaic layer obtained by annealing a precursor layer, wherein the precursor layer comprises metallic precursors, and a second semiconductor layer in order to create a p-n junction with the photovoltaic layer, characterized in that the precursor layer is depo…
