<p><P>PROBLEM TO BE SOLVED: To provide a film substrate for thin film solar cell, a thin film solar cell, and a thin film solar cell module, such that light reception area is expanded, reflection loss is reduced, and photoelectric conversion efficiency of the solar cell is improved by light confinement effect. <P>SOLUTION: The film substrate for the thin film solar cell has a fine concavity and convexity shape formed by arranging regular polygonal pyramids without leaving any gap. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
