Moving further towards ‘green manufacturing’ of photovoltaics

Abstract

As we continue our look at the materials which are making a contribution to the development of photovoltaics, it is timely that we turn our consideration to solders. While these materials are not in themselves photovoltaic, they serve the important role of interconnections and to some extent mechanical linkages. Great changes are in prospect for this humble family of materials, as a result of the need to meet new regulations regarding reduced lead content. ‘Lead-free’ has become a buzzword in the greater electronics manufacturing business, and looks set to bring significant changes to the PV industry.
