Abstract
A fire through conductor paste is applied as a plurality of mutually separate islands on a dielectric layer on a semi-conductor body of a photo-voltaic cell. A connecting structure of a further conductor paste is applied connecting the islands, at least on the dielectric layer between locations of the islands, so that the islands are connected by the connecting structure. Different compositions are used for the fire through conductor paste and the further conductor paste, which behave differently during firing. The fire through conductor paste and the further conductor paste are fired under process conditions wherein the fire through conductor paste fires through the dielectric layer and the further conductor paste does not fire through the dielectric layer. In this way the fire through metal paste establishes electric contact through the dielectric layer between the semi-conductor body and a structure formed from the further conductor paste.
