Flexible and large-area imagers using organic photodetectors

Solution-processed organic photodetectors (OPDs) have a great potential in light sensing and imaging applications. With this emerging technology reaching performances on par with amorphous silicon (a-Si:H) photodiodes, market introduction is imminent. A major R&D focus in further development of OPD technology is therefore to demonstrate the advantages of organic photodiodes in high-resolution, flexible large-area photodetectors. After a survey of the OPD performance, and an introduction of the concepts of active-matrix detectors and their materials, we will present the recent developments at Holst Centre in realizing two prototypical applications, that is, curved X-ray detectors and biometric (fingerprint and palm) scanners.
