Large area flexible organic photodiodes can compete with silicon devices

The performance of large-area flexible organic photodiodes has advanced to the point where they can now offer advantages over conventional silicon photodiode technology, particularly for applications such as biomedical imaging and biometric monitoring that require low-light detection on large areas. The low-noise, flexible organic devices elaborated in solution offer the ability to use arbitrarily shaped large area photodiodes to replace complex arrays that would be required with conventional silicon photodiodes, which can be expensive to scale for large area applications. Organic devices provide performance comparable to that of rigid silicon photodiodes in the visible light spectrum, except in response time. “What we have obtained is the first demonstration that these devices, produced from a solution at low temperatures, can only detect a few hundred thousand photons of visible light every second, similar.
