PURPOSE:To form the rectifying junction and to prevent the crystal selenium layer from being peeled off, by forming the selenium layer after the provision of the cadmium selenide layer on the transparent electrode on the substrate. CONSTITUTION:On the transparent electrode 5 on the glass substrate 4, the cadmium selenide layer 6 split into a plurality is formed. The selenium layer 7 is formed on the cadmium selenide layer 6. On the layer 7, the electrode 8 which has resistive contact with selenium such as tellrium and gold is formed, and uniform selenium layer is obtained with heat treatment after that. When light irradiates the sensor of this construction, electromotive force is produced on the said resistance conact. Further, sequential discharge is made with the switch switched with the scanning pulse, then the time series pulse signal is picked up for the discharge current. |
