PROBLEM TO BE SOLVED: To enhance the photoelectric conversion rate by providing a first electrode made of a linear conductive material, a semiconductor layer laminated coaxially with the first electrode to generate a potential difference between the inner and outer layers upon irradiation with light, and a second electrode formed on the opposite side to the first electrode. SOLUTION: An n-type semiconductor 12, an i-type semiconductor 13 and a p-type semiconductor 14 are deposited sequentially with a first electrode 11 as a central axis and a second electrode, i.e., a transparent electrode 15, is formed at the outer circumferential part. When such a photoelectric conversion element 10 is irradiated with light, a potential difference appears between the electrode 11 and the transparent electrode 15. The electrode 11 is formed of linear material. Each conductor covers other semiconductor with the electrode 11 as a central axis. Since the light receiving surface is formed over the entire circumference, light can be collected efficiently and the photoelectric conversion rate can be enhanced. |
