20 August 2020 Low-noise large-area organic photodiodes
Author Affiliations +
In this talk, we will present organic photodiodes (OPDs) based on polymeric bulk heterojunctions with a level of performance that within the visible spectral range, rivals that of low-noise SiPDs in all metrics, except response time. Large-area OPDs on rigid and flexible substrates retain an unprecedented level of performance. Advantages of OPDs are further illustrated and quantified in a biometric monitoring application that uses ring-shaped, large-area, flexible OPDs, while maintaining low-noise SiPD-level performance. We will discuss how this remarkable performance arises from the selection of photoactive layer materials and by device-geometry optimization without charge-blocking layers.
