摘要：
Two siloxane-containing polyazomethines (PAZx) blended with SiO2 were investigated. SiO2 was obtained by sol-gel method. The size of obtained SiO2 particles was about 408 nm as was confirmed by SEM technique. For the blended with silica polymers absorption UV-vis properties were tested and compare with unblended ones. Electrical behavior of the two kind devices indium tin oxide (ITO)/PAZx : SiO2/Al and ITO/PEDOT : PSS/PAZx : SiO2/Al were tested by impedance spectroscopy in dark and under illumination (halogen lamp, 100 mW/cm(2)) in the frequency range of 1 Hz to 1 MHz with maximum voltage value of 20 mV. For all measured devices, Nyquist plots were presented. PEDOT : PSS interlayer improved electrical properties of made prototype polymeric solar cells. Blending PAZx with silica increased conductivity from 10(-15) to 10(-8) S/cm. (C) 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 128: 691-697, 2013
