20090032107 | ORGANIC SOLAR CELL USING CONDUCTIVE POLYMER TRANSPARENT ELECTRODE AND FABRICATING METHOD THEREOF - The present invention relates to an organic solar cell made of a transparent conductive polymer electrode and a fabricating method thereof. An anode electrode is formed on a substrate, a photoactive layer is formed on the anode electrode, and a cathode electrode is then formed on the photoactive layer. The anode electrode is formed by stacking conductive polymer particles by an electrostatic spray printing method, and a micro pattern is formed on the substrate before forming the anode electrode. The micro pattern is formed by hot embossing, the photoactive layer is formed by gravure printing or spin coating, and the cathode electrode is formed by screen print or evaporation deposition. A series of processes for fabricating an organic solar cell is performed using a roll-to-roll process. | 02-05-2009 |
