A method of manufacturing a solar cell comprising a silicon disc having a region of the n-conductivity type adjoining a major surface, in which an electrode containing silver is provided on the n-type region by means of a silk-screening process, characterized in that during the silk-screening process a paste is used which, in addition to silver, contains an addition in an elementary form, which addition belongs to the group of elements consisting of bismuth, magnesium and indium, that after providing the electrode a thermal treatment in an oxidizing atmosphere is carried out, and that the electrode is then subjected to a chemical or mechanical treatment to improve the junction resistance with the silicon. |
