Organic image sensor have been attracting considerable attention for sensing applications owing toseveral special characteristics compared to semiconductor materials, such as high absorption coefficient, flexibility, stacked structure, and low fabrication cost. By now, our research group reported a color selective organic photoconductive device via a wet process. In this report, we investigated optical characteristics of a blue-sensitive organic photoconductive device by doping several silole derivatives to improve a device performance. We used poly(dioctylfluorenyl-co-benzo-thiadiazole) [F8BT] as a photoconductive and blue
sensitive polymer because of its high carrier mobility and absorption coefficient. Most of silole derivatives
showed only the absorption bands at blue or violet wavelength regions. Therefore, silole derivative is found to be suitable material for a blue-sensitive organic photoconductive device. A maximum external quantum efficiency of 8.9% was obtained by doping 1,1-dimethyl-2,5-bis(N,N-dimethylaminophenyl)-3,4-diphenylsilole in F8BT. This value was two orders higher than that of the reference device with F8BT only.
