METHOD FOR MANUFACTURING A THIN-LAYER PHOTOVOLTAIC DEVICE, IN PARTICULAR FOR SOLAR GLAZING

摘要

A method for producing a thin-film photovoltaic device (1), comprising the following steps: providing a substrate (2); placing a photovoltaic film (3) on said substrate by stacking layers comprising at least a first conductive layer (4) forming a rear electrical contact, a second photoactive layer (5) that is absorbent in the solar spectrum and is made from an inorganic material, and a third layer (6) made from a transparent conductive material forming a front electrical contact; dividing the photovoltaic film into a plurality of individual and interconnected photovoltaic cells (30), forming a plurality of individual holes (31) passing at least through the first and second layers of photovoltaic film in each cell, by applying a mask (8) according to a printing method, in particular material-jet digital printing, flexography, screen printing, or pad printing, said mask having main areas defining a positive or negative stencil for said holes. The present invention is applicable in the field of solar glazing.

1. A method for manufacturing a thin-layer photovoltaic device, comprising the following steps:
a substrate is provided; a photovoltaic film is placed over said substrate by the superposition of layers comprising at least a first conductive layer forming a rear electrical contact, a second photoactive layer absorbing in the solar spectrum based on inorganic material, and a third layer made of transparent conductive material forming a front electrical contact; the photovoltaic film is divided into a plurality of individual and interconnected photovoltaic cells, each cell being connected in series or in parallel with one or several adjacent cell and electrically insulated from the other adjacent cells, said method being characterized in that, upon placing the photovoltaic film, a plurality of individual perforations passing through at least the first and the second layers of the photovoltaic film in each cell is arranged, by the application of a mask according to a printing method, in particular of the type material-jet digital printing, flexography, screen-printing, or pad-printing, said mask presenting main areas defining a positive or a negative stencil of said perforations.
