A method for in-site synthesis of transparent conductive coating of poly(3,4-ethylenedioxythiophene)/nano silver hybrid on transparent substrate is provided. Transparent substrate with oxidant coating containing silver salt is immersed into 3,4-ethylenedioxythiophene (EDOT) solution. The oxidant turns EDOT monomer to poly(3,4-ethylenedioxythiophene) (PEDOT) coating on the transparent substrate; meanwhile, the silver salt itself is reduced to nano silver by the EDOT monomer, resulting in a nano silver-doped PEDOT coating. Thereby, a transparent conductive film made of PEDOT/nano silver coating on transparent substrate is obtained. The transparent conductive film with PEDOT/nano silver coating prepared in the present invention possesses the advantages of high electrical conductivity, optical transparency and environmental stability.

A conductive polymer-metal complex becomes to be adhered simply and strongly on the surface of a substrate such as PTFE. By subjecting a solution containing a monomer which provides a conductive polymer, an anion, and a metal ions such as Ag.sup.+, Cu.sup.2+, Cu.sup.+ and the like to an irradiation with light having an energy required for exciting an electron to an energy level capable of reducing the metal ion, such as ultraviolet light, under an appropriated condition, thereby precipitating the conductive polymer-metal complex as being dispersed in the reaction liquid. By supplying this dispersion liquid onto various substrates, the complex microparticles in the dispersion liquid enter into and mate with the narrow holes on the surface of the substrate. As a result, the complex precipitate formed on the surface of the substrate and the substrate can be adhered strongly to each other.

The present invention relates to a method of preparing high crystalline polythiophene nanowire used for organic solar panels, including the following steps: A. a 0.001-40 wt % polythiophene solution is prepared; B. a 0.01-10 wt % carbon nanomaterial suspension is prepared and a 0.001-5 wt % dispersant is added to the suspension to generate a carbon nanomaterial dispersion; C. The foregoing carbon nanomaterial dispersion is added to the polythiophene solution and the resulting mixture is let stand under atmospheric pressure at 1045 C. for 20400 min so that polythiophene molecules are able to be adsorbed and stacked up on the surface of carbon nanomaterials to generate polythiophene nanowires. Owing to high alignment order and high crystallinity, the polythiophene nanowire is helpful for elevating light conversion efficiency of organic solar panels.
