1. A thick-film paste composition for use in forming an electrical connection in a photovoltaic device comprising a semiconductor substrate having at least one insulating layer on a main surface thereof, the composition comprising:
a) 85 to 99.5% by weight of an electrically conductive metal or derivative thereof, based on total solids in the composition; b) 0.5 to 15% by weight, based on total solids in the composition, of a lead-tellurium-boron-oxide, wherein the lead-tellurium-boron-oxide comprises 0.25 to 5 wt % B2O3; and c) an organic medium; wherein the thick-film paste, when fired, is capable of penetrating the at least one insulating layer. |
