<P>PROBLEM TO BE SOLVED: To provide a composition for forming a p-type diffusion layer capable of forming a p-type diffusion layer with small in-plane variation while reducing internal stress of a silicon substrate and warpage thereof in the manufacturing process of a solar cell using a crystal silicon substrate, and to provide a production method of a composition for forming a p-type diffusion layer, a production method of a p-type diffusion layer, and a manufacturing method of a solar cell. <P>SOLUTION: The composition for forming a p-type diffusion layer contains glass powder containing an acceptor 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 |
