Optoelectronic devices, such as liquid-crystal displays (LCDs), solar cells, and touch panel displays, are indispensable units in many advanced technologies. An optoelectronic device requires at least one electrode to be transparent to emit or harvest light. Indium tin oxide (ITO) is traditionally the popular material as the transparent electrode. However, the scarce indium on the earth and the brittleness of indium tin oxide (ITO) can limit the development of optoelectronic devices. Therefore, there is strong demand for new transparent conductive materials to replace ITO. In this work, we have tried to improve of low conductivity PEDOT:PSS and non-visibility patterned conductivity PEDOT:PSS by using novel materials with photo-reactive group. The conductivity of PEDOT:PSS films was significantly enhanced depended on the amount of novel materials and the photo-reactive difference of novel materials. The mechanism for the conductivity enhancement of PEDOT:PSS with novel materials is attributed to the phase separation of PSS chain from PEDOT:PSS. The properies of the films were analyzed by means of UV-Vis spectroscopy (UV-Vis), 4-probe measurement, fourier transform infrared spectroscopy (FT-IR) and atomic force microscopy (AFM). |
