Abstract
A method of manufacturing a solar electrode comprising steps of:(a) stencil printing a conductive paste onto a front side of a semiconductor substrate through a printing mask comprising: (i) 60 wt % to 95 wt % of a conductive powder, (ii) 0.1 wt % to 10 wt % of glass frit, (iii) 3 wt % to 30 wt % of an organic medium, (iv) 0.4 wt % to 1.7 wt % of an amide compound, based on the total weight of the conductive paste and (b) firing the applied conductive paste to form an electrode.
