Effect of Solvent Dilution on Preparation of PEDOT:PSS Transparent Conductive Films and Device Performance of Organic Solar Cells
4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) films were prepared by using spray coating technique. The morphology
transmittance and conductivity of the film were studied by using ethanol
deionized water
methanol and isopropanol to dilute the origin PEDOT:PSS
respectively. The solvent-diluted PEDOT:PSS films were employed to fabricated organic solar cells. The effect of solvents dilution on the solar cells performance was studied. The results indicate that the introduction of ethanol can effectively inhibit the agglomeration of PEDOT:PSS particles
reduce the film roughness
and improve the transmittance and conductivity of the PEDOT:PSS film. The organic solar cell based on the PEDOT:PSS film diluted with ethanol exhibits a power conversion efficiency of 2.66%
which is higher than those with other diluting solvents.
