Coating material for forming semiconductors, semiconductor thin film, thin film solar cell and method for manufacturing thin film solar cell

Abstract

The present invention aims to provide a coating liquid for forming a semiconductor which facilitates large-area production of a semiconductor that is useful as a semiconductor material of a solar cell with high conversion efficiency and small variation in the conversion efficiency, and enables control of the film thickness. The present invention also aims to provide a semiconductor thin film produced from the coating liquid for forming a semiconductor, a thin film solar cell, and a method for producing the thin film solar cell. The present invention relates to a coating liquid for forming a semiconductor, including a complex that includes a group 15 metal element of the periodic table and sulfur and/or selenium, the coating liquid having a molar ratio of the group 15 metal element of the periodic table to the sulfur and/or selenium of 1:2 to 1:10.
