Description
Solution-processed organic photodetectors (OPDs) are increasingly attractive for light sensing applications as they combine high photogeneration yield with low fabrication costs. Visible-light photodiodes are proposed for use in indirect-conversion X-ray detectors, fingerprint scanners and intelligent surfaces for gesture recognition. Near-infrared (NIR) detectors find applications in biomedical imaging and optical communications.
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. In this presentation, we will present recent developments at Holst Centre in realizing prototypical applications. We will present recent developments in realizing curved X-ray detectors and -upon integration with OLED displays - biometric scanners that can accurately image finger-, palm and vein patterns and simultaneously record PPG signals that can be used to monitor health parameters such as heart beat, oxygen saturation and blood pressure.
