摘要

An i-type amorphous silicon layer 14 and a p-type amorphous silicon layer 15 are formed on a part of an inner wall of a through hole of an n-type single-crystal silicon substrate 11. Further, an i-type amorphous silicon layer 12 and an n-type amorphous silicon layer 13 are formed on a part of the inner wall of the through hole of the n-type single-crystal silicon substrate 11.The inner wall surface of the through hole is covered with the i-type amorphous silicon layer 14 and the i-type amorphous silicon layer 12.
