Abstract
A method of manufacturing a finger electrode for a solar cell, the method including printing a conductive paste on a front surface of a substrate using a printing mask having an opening rate of about 65% or more and baking the printed conductive paste. The conductive paste includes a conductive powder, a glass frit including about 30 mol % to about 60 mol % of tellurium oxide and about 0.1 mol % to about 10 mol % of tungsten oxide, and an organic vehicle.
Claims9
A method of manufacturing a finger electrode for a solar cell, the method comprising:
- (a) printing a conductive paste on a front surface of a substrate using a printing mask having an opening rate of about 65% or more, the printing mask including a mesh, a photosensitive resin layer integrated with the mesh, and an electrode printing portion formed by removing the photosensitive resin layer;
- and
- (b) baking the printed conductive paste,
- wherein the conductive paste includes a conductive powder, a glass frit including about 30 mol % to about 60 mol % of tellurium oxide and about 0.1 mol % to about 10 mol % of tungsten oxide, and an organic vehicle.
