Abstract
AbstractWe reveal the role of phosphorus in contact formation between screen‐printed silver paste and n‐type emitter of industrial silicon solar cells. A higher inactive phosphorus concentration at the emitter surface leads to a larger areal fraction of silver crystallites at the contact. Thus, the specific contact resistivity is reduced. Inactive P atoms support the growth of Ag crystallites into the emitter by leaving the silicon lattice and forming an alloy of Ag/P within the Ag crystallites.magnified image(© 2012 WILEY‐VCH Verlag GmbH & Co.
