Laser micromachining specialist 3D-Micromac said it was supplying Hanwha Q CELLS solar cell plant in Qidong, Jiangsu-province, China with its microCELL OTF laser system for its recently announced transition from Al-BSF (Aluminium Back Surface Field) to PERC (Passivated Emitter Rear Cell) technology.
3D-Micromac launched the second generation of its high-performance microCELL OTF laser systems at SNEC 2017. The high-performance production solution for Laser Contact Opening (LCO) of PERC (Passivated Emitter Rear Cell) solar cells achieves a throughput of 8,000 wafers per hour (wph).
Laser micromachining equipment supplier 3D-Micromac has secured an order from REC Group to supply three ‘microCELL’ OTF laser systems for PERC (Passivate Emitter Rear Contact) solar cells from integrated PV module manufacturer REC Group.
As we conduct our extensive market research phase to define exactly what the industry needs to be discussing and presenting at PV CellTech 2017 in Penang, Malaysia on 14-15 March 2017, one of the top technologies that is certain to be included again is passivated emitter rear contact (PERC) cells.
