A high performance semitransparent organic photodetector with green color selectivity using an organic buffer layer |
| 초록 |
We report green selective transparent organic photodetectors (OPDs) with high detectivity of 2.1 × 1012 cm Hz1/2 /W at a reverse bias of -1 V by adopting inverted structure and using 1,4,5,8,9,11-hexaazatriphenylenehexacarbonitrile (HATCN) as the buffer layer to protect the active organic layers from sputter damage during the deposition of the indium zinc oxide top electrode. The detectivity of the OPDs using 140 nm thick HATCN was comparable to that of the reported conventional OPDs with highly reflective metal electrodes. The green selective transparent OPD using the 140 nm thick HATCN layer showed the transparency of 26% and 60% in the blue region and the red region, respectively. |
