摘要： The area occupied by a photo-sensor element may be reduced and multiple elements may be integrated in a limited area so that the sensor element can have higher output and smaller size. Higher output and miniaturization are achieved by uniting a sensor element using an amorphous semiconductor film (typically an amorphous silicon film) and an output amplifier circuit including a TFT with a semiconductor film having a crystal structure (typically a poly-crystalline silicon film) used as an active layer over a plastic film substrate that can resist the temperature in the process for mounting such as a solder reflow process. A sensor element that can resist bending stress can be obtained.

摘要： A solar battery 10 comprises a metal electrode layer 12, a pin junction 100, and a transparent electrode layer 16 which are successively laminated on a substrate 11 such as a silicon substrate. The pin junction 100 comprises an n-layer 13, an i-layer 14, and a p-layer 15 which are laminated in succession. The i-layer 14 is formed by amorphous iron silicide (FexSiy:H) containing hydrogen atoms.
