Abstract

A photo-electric converting apparatus comprises an array wherein a plurality of photo-electric converting elements are provided, each of which having a semiconductor film layer arranged between an electrode layer and another electrode layer formed on a substrate, and having at least either a rectifying contact or a P-N junction. When the array is irradiated with light under such condition that substantially no bias voltage is applied between the electrode layers of the array, each of the photo-electric converting elements produces forward e.m.f., and forward current flows. A capacitive means in each of the photo-electric converting elements is charged with the forward current, and the capacitive means are discharged successively by scanning pulses, and timed pulse signals are outputted. The present invention discloses further various concrete constructions of the photo-electric converting element and the array thereof with high efficiency of conversion.
