German laser engineering firm 3D Micromac is to provide its laser chopping expertise to Enel Inexperienced Energy’s 3Sun gigafactory in Sicily, Italy as the corporate strives to increase its manufacturing capability of high-efficiency modules to 3GW by 2024.
The microCELL MCS laser chopping system was bought by Bottero S.p.A., which is serving because the engineering, procurement and building (EPC) contractor for the 3Sun undertaking, and might be utilized in Enel’s 3Sun Gigafactory for chopping high-efficiency heterojunction photo voltaic cells.
Bottero stated 3D Micromac was chosen partially due to its patented thermal laser separation course of, which is utilized by the microCELL MCS to offer ablation-free cell chopping that Micromac stated minimised energy losses and supplied superior edge high quality for heat-sensitive heterojunction cells over conventional laser scribe and break processes.
“3D-Micromac’s microCELL programs are confirmed in heterojunction photo voltaic module and cell manufacturing and all of our expertise from these previous installations might be absolutely utilised to assist this main growth undertaking,” stated Uwe Wagner, CEO of 3D-Micromac.
The corporate stated the microCELL MCS laser chopping system has a throughput of greater than 6,000 wafers per hour (full-cells) and is able to chopping mono-crystalline in addition to polycrystalline silicon sq. and pseudo-square wafers ranging in sizes from M2 to M12/G12 into half-cells or shingled cells with out compromising throughput or yield.
One among Europe’s largest PV factories, Enel Inexperienced Energy’s 3Sun Gigafactory produces modules for the corporate’s photo voltaic tasks. In April, the manufacturing facility had a manufacturing capability of 200MW however intends to ramp this as much as 3GW by July 2024.
The power would require €600 million euros (US$631 million) and can see Enel Inexperienced Energy’s funding supported with €118 million (US$124.1) in EU funding by way of the bloc’s Innovation Fund for large-scale tasks.
Enel stated 3Sun’s strains can even produce heterojunction bifacial panels and has teased the event of modules that includes tandem cell buildings sooner or later, however has supplied no particular timeline for this. Whereas heterojunction modules are already commercially obtainable, tandem cells are nonetheless thought-about to be some years away from commercialisation.
