A bias-switchable narrowband/broadband NIR organic photodetector fabricated using a scalable technique

This paper presents a groundbreaking development in the field of organic photodetectors, introducing a novel dual-mode photodetector with exceptional thickness capabilities. The technology is achieved through the innovative use of multilayer blade coating techniques, enabling the seamless transition between narrowband and broadband modes through the application of bias. This pioneering device, termed the "Bias Switchable Narrowband-Broadband Near-Infrared (NIR) Organic Photodetector," is manufactured in ambient conditions and offers several distinct advantages, including dual-mode operation, halogen-free solvent usage, ambient fabrication conditions, and scalability in the manufacturing process.
