8% of total solar cell production presents a defect. Aimen Technology Center, recently announced that it has developed “a laser system to produce optimal photovoltaic modules from solar cells defective.” The system developed is the result of an R + D project called Reptile and thanks to it “we could retrieve all the defective cells produced by the photovoltaic industry,” according to Aimen.

Aimen Galician Technological Centre is leading a European R + D project “so as to develope a laser device designed to repair damaged PV cells during manufacturing process and produce new photovoltaic modules with them, with improved features and custom formats.” Just this week the meeting was held to launch the investigation at the premises of the center O Porrino (Pontevedra, photo). This research has been supported by the Seventh Framework Programme for R & D of the European Union, in which Aimen has different partners in several countries of European Union.

The problem was clearly identified: cells with defect that produces the PV industry, says Aimen, represent up to 8% of total production and “so far the market had no real solution for the reuse of these rejected parts.” Well, according to this Galician Technological Centre, that has been happening, “until now”, because Aimen says they have developed a new device that will produce “new custom-built geometry PV modules for all kind of architectural integration solutions (buildings, infrastructure, signaling) and at low cost” from these cells tared.

The exploitation system of these defective cells is the result of the R + D project named Reptile (Repairing of Photovoltaic Wafers and Solar Cells Enabled by Silicon Laser Processing), an international initiative has been supported by the Seventh Framework Programme for R + D of the European Union, initiative in which Aimen has partners from several countries: ISC Konstanz, a German pointer in solar energy research, and three firms in the photovoltaic field, Solartec (Czech Republic), Ingesea (Spanish), and Enopsys (Greek) . This project, coordinated by Aimen, “provides an automated technique that takes advantage of solar modules damaged by application of laser technology, getting new products with high added value,” says the Galician Technological Centre.

SMEs and laser

According to a statement released this week by Aimen, “In addition, this technique will introduce a new player in the solar power industry: small and medium enterprises (SMEs),” which focuses on small areas of custom photovoltaic application . “Aimen adds , Reptile “also gives the go-ahead to business over the European laser equipment sector, with a new industrial application for them, so this automated device will produce this way a positive impact on all those involved in this field of activity: manufacturers, suppliers, installers, etc. “.
