Noise-Restrained Detection and Fast Response via a Non-Fullerene Acceptor for Stable Operation of Organic Photodiode |
| 초록 |
Emergences of non-fullerene-based acceptors have opened new avenues with regard to improve the figure of merits of organic photodiodes (OPDs) including well-matched energy level and wide absorption based on ultraviolet photoelectron spectroscopy. Herein, eh-IDTBR has been employed in OPDs and the results have been compared with fullerene derivatives (PC71BM), in combination with electron donor PBDTTT-EFT material. eh-IDTBR based OPDs has shown excellent detectivity from 400 nm to 740 nm in comparison to PC71BM based OPDs due to suppressed injected carriers and trap density. Furthermore, morphological and electrical changes depending on thermal and electrical stress have been investigated in the two different acceptor systems. This study elucidates the importance of eh-IDTBR acceptor in OPD and will pave the way for the wavelength specific solution processable non-fullerene-based acceptors based OPDs in the future. |
