Abstract

Strings of solar cells having laser assisted metallization conductive contact structures, and their methods of manufacture, are described. For example, a solar cell string includes a first solar cell having a front side and a back side, and one or more laser assisted metallization conductive contact structures electrically connecting a first metal foil to the back side of the first solar cell. The solar cell string also includes a second solar cell having a front side and a back side, and one or more laser assisted metallization conductive contact structures electrically connecting a second metal foil to the back side of the second solar cell. The solar cell string also includes a conductive interconnect coupling the first and second solar cells, the conductive interconnect including a strain relief feature.
