PURPOSE:To reduce beams projected to a V-CCD channel, and to diminish a smear signal by bringing a light-shielding film into contact with the surface of a photovoltaic element. CONSTITUTION:Light-shielding films 11 consisting of aluminum at the same potential as a semiconductor substrate 7 are brought into contact electrically with a p-type region 9 in an photovoltaic element. According to the constitution, oblique beams projected to V-CCD channels 6 from clearances among the light- shielding films 11 are a semiconductor surface in conventional devices are reflected to the light-shielding films 11 brought into contact with the p-type region in the semiconductor surface, and projected into the photovoltaic element. Consequently, incident oblique beams are not projected directly to the V-CCD channels 6, thus extremely reducing a smear signal. |
