TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The composite comprises 10-80 pts. wt. aqueous dispersion solution containing a conductive polymer solution, 0.3-5 pts. wt. conductivity enhancer, 35-89 pts. wt. solvent, and 0.3-1.5 pts. wt. surfactant comprising 0.01-0.1 pts. wt. fluorosurfactant and having a hydrophilic-lipophilic ratio (hydrophile-lipophile balance, HLB) of more than 12. The ratio of fluorosurfactant and hydrophilic-lipophilic ratio (hydrophile-lipophile balance, HLB) in the surfactant is 1:2-1:30. The hydrophilic or lipophilic group of the fluorosurfactant comprises compound with a main chain or branched chain of perfluoroalkyl group. The surfactant with hydrophilic-lipophilic ratio (HLB) of 12 comprises at least one of ethylene oxide and propylene oxide random copolymer, ethylene oxide and propylene oxide block copolymers, alkyl polyglycol ether, polyoxyethylene alkyl ethers, polyoxyethylene fatty acid esters, polyoxyethylene alkyl phenol ether, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, sucrose fatty acid ester, acetylene glycol and polyoxyethylene ether, preferably acetylene containing compound of formula (Rx-C(CH3)(A)-CC-C(CH3)(A')-Ry) (I), or aryl polyoxyethylene containing compound of formula (II). The solvent comprises water and organic solvent in a ratio of 40:60-90:10. The organic solvent comprises either: 10-50 pts. wt. glycol ethers and 5-80 pts. wt. polyhydroxy alcohols, and 0-10 pts. wt. cyclohexanone. The first electrode of the organic solar cell is a metal mesh.Rx, Ry = H or 1-12C alkyl;A = -(OCH2CH2)m-OH;A' = -(OCH2CH2)n-OH;m, n = 1-80;R1, R2 = H or 1-12C alkyl, preferably 1-12C alkyl; andp = 1-200. EXAMPLE - 30.6 pts. wt. Aqueous dispersion solution including poly(3,4-ethylenedioxythiophene)-poly(4-styrenesulfonate) with 1 pt. wt. solid content and 1.6 pts. wt. dimethyl sulfoxide were added into water and mixed for 2 hours. Then water, diethylene glycol monobutyl ether and propylene glycol in a ratio of 5:2:3 were mixed with 66.75 pts. wt. solvent and 1 pt. wt. surfactant containing 0.05 pts. wt. fluorosurfactant for 4 hours to obtain the conductive polymer ink composition.
