DOI: 10.1002/adfm.202001402
Abstract: Herein, non‐fullerene acceptor‐based organic photodiodes are compared with fullerene acceptor‐based organic photodiodes. The non‐fullerene acceptor, ethylhexyl‐rhodanine‐benzothiadiazole‐coupled indacenodithiophene (eh‐IDTBR)‐based organic photodiodes show a higher detectivity (1.61 × 1013 cm Hz1/2 W−1) and a faster response time… read more here.
