||SOMERSET, NJ - Alpha Assembly Solutions, the world leader in the production of electronic soldering and bonding materials, is participating in the upcoming Intersolar India taking place December 5-7 in Mumbai, India, where global experts focus on photovoltaics, PV production technologies, energy storage systems and solar thermal technologies.
Narahari Pujari, R&D Manager for Alpha Assembly Solutions, part of the MacDermid Performance Solutions group of businesses, will present a technical paper on Lead-Free Soldering to the cSi Cell Stringing Process that focuses on PV market, current trends in the development of lead-free solutions and the impact on manufacturing costs by transitioning away from lead-based solder alloys, which are currently in use predominantly due to their sufficiently low melting points and ability to make reliable solder joints.
“Lead-containing alloys are not only toxic, but can result in hazardous waste classification for PV modules at the end of shelf-life, thus increasing costs overall when safe disposal efforts are included”, said Pujari. “In order for the market to embrace the adaptation of lead-free alloys, we must first discuss the market drivers and understand the technological and manufacturing challenges involved with such a migration”.
Various available technologies are critically assessed in Pujari’s technical presentation which finds that although there is currently no data on long-term reliability of PV modules using lead-free alloys, there is sufficient evidence that supports its likelihood. Additionally, lead-free solders for PV ribbon are proving to be cost and energy-efficient.
