چکیده انگلیسی
Organic-inorganic hybrid electronics have attracted considerable attention because of the possibility of combining advantages of both the organic and inorganic devices. High-performance hybrid optocouplers made of the a-Si:H pin photodiode and organic light emitting diodes have been fabricated and studied. With a blue organic light emitting diode as the light source, the optocoupler shows good photoresponse with a current transfer ratio of 3.72% at the photodetector bias of â2Â V and a large light/dark current ratio of 5.6Â ÃÂ 106. With a high efficiency tandem white organic light emitting diode as the light source, an even higher current transfer ratio of 10.7% was achieved, which is larger than that of the all-organic optocoupler and is comparable to that of the all-inorganic optocoupler. Influences of different wavelength components ratios of the OLED spectrum on the photoresponse of a-Si:H pin photodiode was also investigated. It shows that the selection of OLED wavelength plays important roles in improving the performance of OOC. This kind of organic-inorganic hybrid system can be used in many electronic and optoelectronic products.
