CONDUCTIVE PASTES WITH ORGANOMETALLIC MODIFIERS Russian patent published in 2013 - IPC C09D11/00 H01L31/216 

FIELD: chemistry.

SUBSTANCE: conductive paste contains frit glass, a conductive material, an organic medium and one or more organometallic components which form metal oxides when burnt. The organometallic components are selected from a group comprising a metal carboxylate and a metal alkoxide, where the metal is boron, aluminium, silicon, bismuth, zinc or vanadium. When deposited on antireflecting coating on a substrate, the conductive paste is capable of penetrating the coating to form an ohmic contact with the substrate. Described also is a photovoltaic cell, having a semiconductor substrate, an antireflecting coating and lines of a conductive mesh formed from said conductive paste.

EFFECT: high efficiency of the photovoltaic cell, improved adhesion and ohmic contact between metallic elements and the substrate through antireflecting coatings.
