<p><P>PROBLEM TO BE SOLVED: To supply a solar cell that has no unevenness on the surface thereof and is visually excellent and superior in conversion efficiency. <P>SOLUTION: The solar cell uses crystal silicon, and the surface shape of one crystal grain on the light incident surface of the crystal silicon is divided into two or more areas. The surface shape of the one crystal grain is divided into two or more areas by one-time anisotropic etching, and a difference of unevenness on the light incident surface is≥20μm and≤200μm. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
