<P>PROBLEM TO BE SOLVED: To provide an n-type diffusion layer forming composition excellent in dispersion stability, capable of forming an n-type diffusion layer at a specific portion without forming an unnecessary n-type diffusion layer, in a manufacturing process of a solar cell using a crystalline silicon substrate; a method for manufacturing an n-type diffusion layer; and a method for manufacturing a solar cell. <P>SOLUTION: An n-type diffusion layer forming composition includes glass powder containing a donor element; a binder having a weight average molecular weight of 5,000 or more and 500,000 or less; and a solvent. An n-type diffusion layer and a solar cell having an n-type diffusion layer are manufactured by applying the n-type diffusion layer forming composition and subjecting the n-type diffusion layer forming composition to heat diffusion treatment. <P>COPYRIGHT: (C)2012,JPO&INPIT |
