Patent ID: 8691326

Claim:
A method for manufacturing a solar cell electrode, comprising the steps of: (a) applying a conductive paste for bus electrode to a wafer in order to form a bus electrode pattern; (b) depositing onto the wafer a photocurable conductive paste for finger electrode from a discharge slot of a dispenser nozzle to thereby form an uncured finger electrode pattern on the wafer, wherein the nozzle moves parallel to the wafer; and (c) curing the uncured finger electrode pattern by exposing the uncured finger electrode pattern to UV light either after forming the uncured finger electrode pattern on the wafer in the step (b), or concurrent with the step (b), and further comprising a step (d) of firing the cured electrode pattern after the step (c), wherein the photocurable conductive paste for finger electrode comprises conductive metal particles, glass frits, a cross-linkable compound, a photopolymerization initiator and an organic solvent, and wherein the cross-linkable compound is 1.0 to 20.0 wt %, the photopolymerization initiator is 0.2 to 15.0 wt % and the organic solvent is above 1.0 wt % based on the total weight of the photocurable conductive paste for finger electrode, and wherein a solvent with a boiling point of 85° C. or more constitutes more than 90 wt % of the organic solvent composition, and wherein the content of inorganic solids of the conductive paste for bus electrode is higher than the content of inorganic solids of the photocurable conductive paste for finger electrode.
