<P>PROBLEM TO BE SOLVED: To provide a p-type diffusion layer forming composition, a manufacturing method of a p-type diffusion layer, and a manufacturing method of a solar cell element, capable of forming a p-type diffusion layer while suppressing roughening of a substrate surface, without generating internal stress of a silicon substrate and warpage of a substrate in a manufacturing process of a solar cell element using a semiconductor substrate. <P>SOLUTION: The p-type diffusion layer forming composition contains silicon particles, dispersion media, and glass powders containing acceptor elements. A p-type diffusion layer and a solar cell element having the same can be manufactured by coating the p-type diffusion layer forming composition and treating with thermal diffusion. <P>COPYRIGHT: (C)2013,JPO&INPIT |
