Abstract
PURPOSE:To raise the utilization factor of incident light by arranging a plurality of thin film photosensors at the inclines of a V-shaped groove(s) provided on a substrate. CONSTITUTION:One or plural V-shaped grooves 2 are provided on a substrate 1 such as glass, ceramic or the like and a plurality of thin film photosensors 3 are provided at the inclines of the groove(s) 2. The photosensors 3 are constituted by evaporating the first electrode film 4, a photoconductive film 5 and the second electrode film 6 and by stacking them in order by sputtering or the like. The hetero junction of a II-IV group compound such as CdS-CdTe or the like and the substance of amorphous chalcogenites such as SnO2-As.Se.Te or the like are used as the film 5. In this way, the utilization factor of incident light is increased by widening a carrier growth region. It may also be possible to provide the thin film photosensors at one side of the inclines of the groove and install a metal thin film feeding light to the photosensors by reflecting the incident light at the other incline.
