Organic photonic devices like organic photodetectors (OPDs) and organic photovoltaics (OPVs) have interested researchers due to their advantage of thin thickness, flexibility and solution process ability, unlike inorganic material based devices. However the devices fabrication strategy for OPDs were not much studied unlike OPVs. We have fabricated the organic photodiode devices with a donor conjugated polymer PDTBTBz-2Fanti, and Y6 as an acceptor. By dissolving organic photoactive materials with solvent additives, the morphology of the blend films can be controlled. The device with pristine film has a detectivity of 2.18×1013 at -2V. However, the device with 1-chloronaphthalene (CN) treated film has a comparably a higher PCE of 8.41% and detectivity of 3.02×1013 at -2V due to the decrease in dark current. This study suggests about the morphology control strategy for organic photodetectors and organic photovoltaics. |
