CONDUCTIVE PASTE AND SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2017/154612
Kind Code:
A1
Abstract:
Provided is a conductive paste which is used for the purpose of forming an electrode for electrical connection to a p-type semiconductor layer of a crystalline silicon solar cell, and which is able to fire through an anti-reflection film during firing and is capable of forming an electrode having a low contact resistance on a p-type semiconductor layer.
A conductive paste for the formation of an electrode of a solar cell, which contains (A) a conductive powder, (B) an Al powder or Al compound powder having an average particle diameter of 0.5-3.5 μm, (C) a glass frit and (D) an organic medium, and which contains 0.5-5 parts by weight of (B) the Al powder or Al compound powder per 100 parts by weight of (A) the conductive powder.
