| Summary: | 碩士 === 國立虎尾科技大學 === 電子工程系碩士班 === 102 === In this study, the multiple processing for improvement of PEDOT: PSS films were investigated. The PEDOT: PSS solution was improved by doping organic solvent. The sheet resistance of PEDOT: PSS film was decreased from 140 to 58.7 ohm/square with the increasing time of heating-stirred. It was reduced nearly 58%. The improvement of doping effect was attributed to induce the reorientation of PEDOT grains and PSS chains in PEDOT: PSS solution. And PEDOT grains and PSS chains were aggregated gradually in the heating-stirred process. The PEDOT: PSS film was used as the anode of solar cell to replace ITO film. The basic device structure was fabricated as follows: PEDOT: PSS/ CuPc/ C60/ BCP/ Ag. The PCE of organic solar cell was used for verification of the formula of merit values. The best value of the φTC is 3.04×10-3 ohm-1 square. And the best PCE of organic solar is 0.203%. The PCE of organic solar is consistent with the merit value. This indicates that the merit value can be represented for the PCE of organic solar cell.
Based on the optimal conductivity of PEDOTPSS film, we improved surface of PEDOT: PSS film by using the acid solution. After treatment of acid solution, the sheet resistance of PEDOTPSS film can be further decreased from 58.7 to 43 ohm/square. In addition, the transmittance of PEDOTPSS film was slightly increased from 77.2% to 82.6% in the visible wavelength range from 400 to 700 nm. The conductivity is further enhanced because the surface of PEDOT: PSS films were relatively more PEDOT conductive grains after treatment of acid solution.
