Novel low-bandgap polymers were synthesized as photodetecting materials based on 2,1,3-benzothiadiazole-5,6-dicarboxylic imide.
Solution-processed polymer photodetectors were fabricated.
The dark current was effectively repressed with an electron-extracting and hole-blocking layer of C60.
The PDIC20-BTh photodetector exhibited high detectivities (∼1012 Jones) covering UV–vis−NIR region.
