Title:
COMPOSITION FOR FORMING ELECTRODE OF SOLAR CELL, AND ELECTRODE MANUFACTURED USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/104623
Kind Code:
A1
Abstract:
The present invention relates to a composition for forming an electrode of a solar cell, comprising: a silver (Ag) powder; glass frit containing about 0.1 mol% to about 50 mol% of a silver element; and an organic vehicle, wherein the silver element is derived from silver halogenide (Ag-X). The composition for forming an electrode of a solar cell of the present invention provides improved contacting properties of an electrode with a wafer by introducing the silver halogenide in the glass frit. An electrode of a solar cell manufactured by using the composition has minimized contact resistance, contact specific resistance, and series resistance, thereby increasing conversion efficiency of a solar cell.
