P-TYPE IMPURITY DIFFUSION COMPOSITION, METHOD FOR MANUFACTURING SEMICONDUCTOR ELEMENT USING SAID COMPOSITION, SOLAR CELL, AND METHOD FOR MANUFACTURING SAID SOLAR CELL

摘要

The purpose of the present invention is to provide a p-type impurity diffusion composition with which it is possible to improve storage stability of a coating liquid, and to achieve uniform diffusion of the coating liquid on a semiconductor substrate. In order to achieve the above-mentioned purpose, the present invention has the following composition. Namely, a p-type impurity diffusion composition characterized by including (A) a group-13 element compound, (B) a hydroxyl-group-containing polymer, and (C) an organic solvent, (C1) a cyclic ester solvent being contained as the organic solvent.
