Technical Data Sheet
Product description
AL8866 is a series of aluminum pastes developed for use as the back electrode on single or polycrystalline silicon solar cells. This low bow aluminum paste is specially designed to form p+ doped layer when fired on a p-doped silicon (<200 microns) photovoltaic devices. This paste has been optimized to eliminate Al bead formation during the firing process.
