Here we report the effects of surfactant-capped MoO3 nanoparticles (NPs) to improving interfacial contact between the active layer and MoO3 layer for achieving high performance photo diode. For this purpose, MoO3 NPs capped with various surfactants such as sodium dodecyl sulfate (SDS), polyethylene glycol dodecyl ether, Polyethylene glycol oleyl ether, polyoxyethylene(10) oleyletherb and polyethylene glycol hexadecyl ether were synthesized. By constructing electron blocking layer with surfactant-capped MoO3 NPs, we show improved morphology and low dark current density, leading to high detectivity without sacrificing the photocurrent. The origin of such enhanced performances of organic photodiodes is fully discussed together with various characterization results. |
