EFD was awarded the 2009 International Solar Cell Award for the Best Technical Product for Photovoltaic Module Assembly. The award was presented at the 2009 InterSolar Exhibition in Munich, Germany with over two-thousand registered industry participants and nine expert industry judges voting EFD's PV Cell Ribbon and Bus Bar Attachment Methodology is a point-to-point soldering process that uses a proprietary lead-free solder paste and flux mixture to attach string ribbon material to silver bus bars during module assembly. In addition to eliminating the need for pre-coating of ribbon material with liquid flux, the additional metal content augments the solder joint. The method is compatible with both manual and automated assembly operations.
