<p><P>PROBLEM TO BE SOLVED: To provide a composition for forming an n-type diffusion layer which can form an n-type diffusion layer with small in-plane variation at a specific part without forming unnecessary n-type diffusion layer in the manufacturing process of a solar cell using a crystal silicon substrate, and to provide a production method of a composition for forming an n-type diffusion layer, a production method of an n-type diffusion layer, and a manufacturing method of a solar cell. <P>SOLUTION: The composition for forming an n-type diffusion layer contains glass powder containing a donor element and a dispersion medium, wherein the frequency distribution of the glass powder in volume reference has a plurality of maximum peaks, and in any two maximum peaks out of the plurality of maximum peaks, particle size of the maximum peak on the small diameter side is equal to 0.01-0.50 times that of the maximum peak on the large diameter side. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
