<p><P>PROBLEM TO BE SOLVED: To provide a silicon based thin film solar cell in which conversion efficiency is enhanced. <P>SOLUTION: The thin film solar cell has such a structure as one to ten layers of a laminate 10 consisting of a p-type microcrystal thin film 3 principally comprising silicon or germanium, an i-type microcrystal ultrathin film 7 having a band gap larger than that of the p-type microcrystal thin film 3, and an i-type amorphous ultrathin film 8 are inserted at the junction interface of an n-type microcrystal thin film 3 and an i-type microcrystal thin film 4 of at least one pin junction. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
