Title:
CONDUCTIVE PASTE COMPOSITION FOR SOLAR CELLS
Document Type and Number:
WIPO Patent Application WO/2013/018462
Kind Code:
A1
Abstract:
Provided is a conductive paste composition for solar cells that makes it possible to simplify control of the penetration amount of an electrode material during the fire-through process, and to easily obtain an ohmic contact. The solar cell (10) has a light-receiving surface electrode (20) formed by the fire-through method, and the light-receiving surface electrode (20) is configured from a thick-film silver containing glass that contains SO2 in the amount of 0.05-5.0 mol%; hence, the thick-film silver paste reduces viscosity when the glass softens while maintaining favorable corrosion resistance, without adding alkali metals such as Li, Na and K, or changing the composition. Therefore, a thin, uniform glass layer is formed at the interface between the light-receiving surface electrode (20) and an n-layer (14); hence, it is possible to obtain a solar cell having excellent electrical properties.
