<p><P>PROBLEM TO BE SOLVED: To provide a solar cell, where grooves and electrodes are easily provided and which is improved in conversion efficiency by restraining carriers from being recombined in the grooves. <P>SOLUTION: A light receiving plane is formed on the one surface of a crystal semiconductor substrate, and p-type semiconductor layers 19 and n-type semiconductor layers 20 are alternately provided on the other surface of the semiconductor substrate for the formation of the solar cell 10. The p-type semiconductor layers 19 and the n-type semiconductor layers 20 are alternately provided in V-shaped grooves 18, which are cut in the other surface of the semiconductor substrate and triangular in cross section, and the V-shaped grooves 18 are filled with the same electrode material. <P>COPYRIGHT: (C)2004,JPO</p> |
