PROCESS FOR THE PRODUCTION OF LFC-PERC SILICON SOLAR CELLS

摘要

A process for the production of a LFC-PERC silicon solar cell having an aluminum back electrode wherein an aluminum paste having no or only poor fire-through capability and including particulate aluminum, glass frit, an organic vehicle and 0.01 to <0.05 wt. % of at least one antimony oxide, based on total aluminum paste composition, is used, and wherein the at least one antimony oxide is present in the aluminum paste as separate particulate constituent(s) and/or as glass frit constituent(s).
