P-TYPE DIFFUSION LAYER FORMATION COMPOSITION, AND SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a p-type diffusion layer formation composition capable of forming a p-type diffusion layer and a back electrode while suppressing occurrences of internal stress in a silicon substrate and substrate warpage, in a manufacturing process of a solar cell using a crystal silicon substrate, and to provide a solar cell formed by using the p-type diffusion layer formation composition.

SOLUTION: A p-type diffusion layer formation composition includes: metal particles; glass particles containing an acceptor element; a resin; and a solvent. A solar cell is provided with a p-type diffusion layer and an electrode that are formed by heat treatment after the p-type diffusion layer formation composition is applied on a semiconductor substrate.
