Abstract

Tunneling atomic force microscopy (TUNA) was successfully used to confirm that electro-devices based on TiO 2-SEO nanocomposites can find possible application in solar power conversion field. Investigated electro-devices show different current flow depending on the layer combination. The highest capacity was shown by the electro-devices with a PEDOT-PSS layer on the top, being the average current values ∼200 pA at 10 V applied voltage. The conductivity value measured by Keithley indicated that the system ITO/1:PEDOT-PSS/1:TiO 2-SEO electro-device shows the highest conductivity level, 0.16 S/cm. Thus, these systems have high potential to find application as solar cell devices.
