Document Type and Number:
WIPO Patent Application WO/2015/076157
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing a conductive composition which enables good electrical bonding when an electrode of a solar cell is formed.
[Solution] A method for producing a conductive composition for forming an electrode of a solar cell, which comprises: a step for preparing a silver powder, a tellurium-containing composition and a tellurium valence adjustment material; and a step for producing a conductive composition by adjusting the blending ratio of the silver powder, the tellurium-containing composition and the tellurium valence adjustment material so that the average valence of tellurium (Te) contained in the interface between a substrate of a solar cell and the conductive composition is from 4.3 to 5.1 (inclusive) if the conductive composition is applied over the substrate and fired thereon.
