<p><P>PROBLEM TO BE SOLVED: To provide a photoelectric conversion device capable of enhancing light absorption efficiency and lowering manufacturing costs. <P>SOLUTION: The photoelectric conversion device has a light receiving hole 3 bored in a light receiving surface of a single-crystal silicon substrate 1, the light receiving hole 3 including a bottom portion having two bottom surfaces 81, 82. Then, the light receiving hole 3 has a minimum depth of and an maximum length of an opening of the light receiving hole 3, and tilt angles of the bottom surfaces 81, 82 of the bottom portion thereof set so that light entering the light receiving hole 3 is reflected at least twice in the light receiving hole 3. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
