High-Performance All-Polymer Solar Cells and Photodetectors …
All-polymer solar cells (all-PSCs) and all-polymer photodetectors (all-PPDs) are promising for application in flexible electronics, but their performance is greatly limited by the lack of polymer acceptors and the difficulties in morphology control. Herein, we report the use of a high-mobility n-type polymer semiconductor, PNDI-DTBT, for …
Low dark current with high-speed detection in a scalable …
This study presents the effect of photodetector device area on the figures of merit (FOMs). The dark current and rise time increase with the device''s active area and limit the photodetector''s detectivity. To overcome this tradeoff, we designed a self-assembled monolayer-based hole transport layer for scaling up the active area while …
