<P>PROBLEM TO BE SOLVED: To provide a diffusion layer formation composition, a manufacturing method of a diffusion layer, and a manufacturing method of a solar cell element capable of forming a diffusion layer without causing an internal stress and a warpage in a silicon substrate in a manufacturing step of a solar cell element using the silicon substrate. <P>SOLUTION: An impurity diffusion layer formation composition contains a glass powder including a donor element or an acceptor element and a dispersion medium. An n-type diffusion layer or a p-type diffusion layer and a solar cell element having the n-type diffusion layer or the p-type diffusion layer are manufactured by coating this impurity diffusion layer formation composition on a semiconductor substrate and performing thermal diffusion treatment. <P>COPYRIGHT: (C)2013,JPO&INPIT |
