摘要:
In an optical sensor device employing an amorphous silicon photodiode, an external amplifier IC and the like are required due to low current capacity of the sensor element in order to improve the load driving capacity. It leads to increase in cost and mounting space of the optical sensor device. In addition, noise may easily superimpose since the photodiode and the amplifier IC are connected to each other over a printed circuit board. According to the invention, an amorphous silicon photodiode and an amplifier configured by a thin film transistor are formed integrally over a substrate so that the load driving capacity is improved while reducing cost and mounting space. Superimposing noise can be also reduced.

An object is to provide a photoelectric conversion device capable of detecting a wider range of illuminance without expansion of a range of an output voltage or output current. The photoelectric conversion device has a photoelectric conversion device including a photoelectric conversion element and an amplifier circuit electrically connected to the photoelectric conversion element, and a bias switching unit for reversing a bias to be applied to the photoelectric conversion device. The bias to be applied to the photoelectric conversion device is reversed with use of the bias switching unit, whereby the photoelectric conversion device can detect a wider range of illuminance without expansion of a range of an output voltage or output current.

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.

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. In the i-layer 14, at least a part of the hydrogen atoms contained therein terminate dangling bonds of silicon atoms and/or iron atoms, so that a number of trap levels which may occur in an amorphous iron silicide film can be eliminated, whereby the i-layer 14 exhibits a characteristic as an intrinsic semiconductor layer.

The present invention relates to a photoelectric conversion device having a photodiode having a photoelectric conversion layer, an amplifier circuit including a thin film transistor and a bias switching means, where a bias which is connected to the photodiode and the amplifier circuit is switched by the bias switching means when intensity of incident light exceeds predetermined intensity, and accordingly, light which is less than the predetermined intensity is detected by the photodiode and light which is more than the predetermined intensity is detected by the thin film transistor of the amplifier circuit. By the present invention, light ranging from weak light to strong light can be detected.

Thereby an electrode layer and an insulating isolation layer can be thinned.
