FoilMet® - Connect: A New Rear Metallization Upgrade for PERC and other Cell Concepts
In this contribution the novel aluminum foil based rear metallization technology FoilMet® - Connect is introduced. With this technology, we combine the optical advantages of a foil metallized rear, known from FoilMet® - Classic and the high voltages of screen printed and furnace fired contacts usually applied in industrial PERC. The applied paste volume is reduced in the FoilMet® - Connect technology which we show to come with benefits in contacts formation during the firing process in a standard belt furnace. With this technology, we report an improvement in cell efficiency by Di = (0.25±0.15) %abs over a mono facial screen printed PERC. Therefore it is a high efficiency upgrade for most monofacial cell concepts based on screen printed metallization.
