N-TYPE DIFFUSION LAYER FORMATION COMPOSITION, MANUFACTURING METHOD OF N-TYPE DIFFUSION LAYER, AND MANUFACTURING METHOD OF SOLAR CELL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an n-type diffusion layer formation composition, a manufacturing method of an n-type diffusion layer, and a manufacturing method of a solar cell element capable of forming an n-type diffusion layer in a specific part without forming the n-type diffusion layer in an unnecessary region in a manufacturing step of a solar cell element using a silicon element and obtaining a sufficient ohmic contact by a simplified step.

SOLUTION: An n-type diffusion layer formation composition contains a glass powder including a donor element and a dispersion medium. An n-type diffusion layer and a solar cell element having this n-type diffusion layer are manufactured by coating this n-type diffusion layer formation composition on a semiconductor substrate and performing thermal diffusion treatment.
