Imec presented several large-area silicon solar cells with a conversion efficiency above 19%. Two types of cells were realized namely with Ag-screenprinted contacts and plated Cu-contacts. Efficiencies of cells with screenprinted contacts were up to 19.1% whereas 19.4% was obtained with Cu-plated contacts. These high efficiencies were obtained thanks to several factors amongst which a combination of improved texturization and optimized firing conditions. The results were achieved on large-area cells (148cm^2 which is 22.94 square inches. About 6 inches by 4 inches) with 170µm thickness, proving the industrial viability of the process.
