High crystalline polythiophene nanowire for organic solar panels and method of preparation thereof

A method of preparing high crystalline polythiophene nanowire for organic solar panels, including the following steps:

• A. polythiophene is dissolved in the first organic solvent to generate a 0.001-40 wt % polythiophene solution, wherein the first solvent is a solvent selected from toluene, xylene and chloroform or mixtures thereof;
• B. a carbon nano-material is added to the second organic solvent to generate a 0.01-10 wt % carbon nano-material suspension, wherein the second organic solvent is one solvent selected from toluene, xylene and chloroform or mixtures thereof and a 0.001-5 wt % dispersant is added to the suspension to generate a carbon nano-material dispersion;
• C. the carbon nano-material dispersion is added to the polythiophene solution and the resulting mixture is let stand under atmospheric pressure at −10˜45° C. for 20˜400 min so that polythiophene molecules are able to be adsorbed and stacked up on the surface of carbon nano-materials to generate high crystalline polythiophene nanowires, wherein the mixing ratio of the polythiophene solution to the carbon nano-material dispersion falls in the range between 1:0.01 and 1:10.
