EFD, a subsidiary of Nordson Corporation has been 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. 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. According to EFD president Peter Lambert, “Winning the Cell Award affirms EFD’s traditional approach of thoroughly researching industry needs and developing creative solutions that enable manufacturers to meet the needs of their customers as efficiently and cost effectively as possible.
The process has shown a reduction in the amount of microcrack formation and aids in the verification of solder joint formation during module assembly, increasing the life of the solar module. Additionally, EFD’s proprietary solar alloy increases solder joint toughness, consistency and durability.
