INK FOR SOLAR CELL AND MANUFACTURING METHOD OF THE INK, AND CIGS FILM SOLAR CELL USING THE INK AND MANUFACTURING METHOD THEROF

摘要

An ink for forming a thin film of solar cell and a manufacturing method of the ink, and a CIGS film solar cell using the ink and a manufacturing method thereof are provided enhance the performance of the solar cell by increasing the light-to-electric energy conversion efficiency. An ink(101) for forming a thin film of solar cell comprises the organic solvent, the selenium selected from a group consisting of the copper, the indium, and the gallium and a nano particle having the sulfur. The manufacturing method of the ink for the thin film composition of the solar cell comprises the step of manufacturing the mixture of the nano particle; the step of performing the thermal process to the organic solvent. The thermal process of the nano particle ink transforms the nano particle ink to the light absorption layer. The nano ink functions as the light absorption layer.
