Abstract

original image

An organic optocoupler composed entirely of small molecules is shown to exhibit the highest current-transfer ratio reported to-date. Based on a photosensitive C60/NPB interfacial heterojunction, its frequency response is also significantly better than in previously reported systems. It suggests a new way in which organic optocouplers that behave comparably to commercial inorganic optocouplers may be achieved.
