In this talk, we will discuss a detailed study of the performance of organic photodiodes (OPDs) based on polymeric bulk heterojunctions. We will show that their performance is comparable with that of low-noise SiPDs in all metrics, except response time within the visible spectral range. Furthermore, OPDs present significant advantages over their inorganic counterparts since they can be fabricated on flexible substrates and their level of performance remains unprecedented even when their area is increased. 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.
