Non-fullerene-based organic photodetectors for infrared communication

Journal article

Benefiting from the progress of organic solar cells (OSCs), organic photodetectors (OPDs), devices that convert a light signal into an electrical signal, have shown in parallel rapid improvement.1–3 OPDs have potential be used for a wide range of application such as imaging,4–7 artificial vision,8,9 wearable electronics,10,11 medical monitoring12 or light communication.13 Historically the development of OPDs has largely focused on detection of visible light, however, the research effort has recently moved towards IR light with applications in biomedical monitoring, imaging or communication.11,14,15 Even though IR OPDs were successfully implemented in the ubiquitous photoplethysmogram sensors,14,16 other examples of real-life applications have been very limited.11,17 To demonstrate the potential of organic materials for IR detection, it is essential to incorporate them on other technologies, IR communication being one of them.The research reported in this publication was supported by funding from King Abdullah University of Science and Technology Office of Sponsored Research (OSR) under awards no.
