Method of manufacturing solar cell electrode

摘要

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.

1. 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, the conductive paste comprising:
(i) 60 wt % to 95 wt % of a conductive powder,(ii) 0.1 wt % to 10 wt % of a 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 wherein the amide compound is a fatty acid diamide represented by the formula: R′—CO—NH—R″—NH—CO—R′, wherein R′ independently represents an substituted or unsubstituted aliphatic chain of a fatty acid, and R″ represents an substituted or unsubstituted alkylene group.
