Claim:
1. A method of preparing high crystalline polythiophene nanowires for organic solar panels, including the following steps: (a) dissolving polythiophene in a first organic solvent to generate a 0.001-40 wt % polythiophene solution, wherein the first organic solvent is selected from the group consisting of toluene, xylene, chloroform and mixtures thereof; (b) adding a carbon nano-material to a second organic solvent to generate a 0.01-10 wt % carbon nano-material suspension, wherein the second organic solvent is selected from the group consisting of toluene, xylene, chloroform and mixtures thereof, and adding 0.001-5 wt % of a dispersant to the suspension to generate a carbon nano-material dispersion; (c) adding the carbon nano-material dispersion to the polythiophene solution and allowing the resulting mixture to stand under atmospheric pressure at −10˜45° C. for 20˜400 minutes so that the polythiophene molecules are able to be adsorbed and stacked up on the surface of the carbon nano-material 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; (d) extracting the polythiophene nanowires from the mixture of the polythiophene solution and the carbon nano-material dispersion and removing the polythiophene molecules that are amorphous and adsorbed on the surface of the polythiophene nanowires with a neutral organic solvent, wherein the said neutral organic solvent is cyclohexane or methylcyclohexane; and (e) adding the polythiophene nanowires treated by the neutral organic solvent to a solution containing a minor content of polythiophene and a major content of a mixture of carbon nano-tube, graphene and carbon nano-capsule to enable the mixture to be filled between the polythiophene nanowires, wherein the mixture has mixing ratio of carbon nano-tube to graphene to carbon nano-capsule that is 0.2:0.3:1 or 0.4:0.2:1.
