<p><P>PROBLEM TO BE SOLVED: To provide a substrate for a thin film solar cell, which has high light confinement effect and reflectivity and whose surface shape is flat to such a degree that it does not exert a bad influence on a power generation layer formed thereupon. <P>SOLUTION: On the substrate 1 for the thin film solar cell, the power generation layer 2, and a transparent conductive film 9 and a silver electrode 10 forming an upper electrode are formed. The substrate 1 for the thin film solar cell includes a high-reflectivity substrate 3 having a high-reflectivity reflecting surface on a surface and a transparent and conductive composite film formed thereupon. The transparent composite film is formed by dispersing and arranging, in a substrate in-plane direction, two or more kinds of materials, for example, a high-reflectivity material 4 and a low-reflectivity material 5 which are transparent and different in reflectivity to light in the visible range to the near-infrared range, and at least one of the high-reflectivity material 4 and low-reflectivity material 5 has conductivity. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
