Synthetic Approach to Achieve a Thin Film Red-Selective Polymer Photodiode: Difluorobenzothiadiazole-based Donor-Acceptor Polymer with Enhanced Space Charge Carriers |
| 초록 |
A synthetic strategy to accelerate charge collection narrowing (CCN) of polymer photodiode so that well-defined color selectivity can be realized even with thin film thickness. A new polymer semiconductor POFPhDT2FBT is synthesized by copolymerizing difluorobenzothiadiazole acceptor with also difluorinated donor moiety. A polymer photodiode renders a high peak detectivity of ~6.0×1012 Jones at 650 nm with narrow band red-selective spectral response, implying that CCN is successfully achieved. This study shows the feasibility of efficiently realizing color selectivity of polymer photodiode even at a film thickness of 500 nm of the active layer |
