Preparation of Conductive Ink for Organic Solar Cell Electrode

摘要

The preparation method of conductive ink is introduced, with silver acetate as the precursor and dodecylamine (DDA) as the protective agent. The sheet resistance of the sintered conductive pattern varies at different temperature and it is lower than 1 Ω/□ when the sintering temperature is higher than 130°C. Three different methods of blade-coating, spin-coating, ink-jet printing are used to fabricate the electrodes of solar cells. It is found that the morphology of the electrode made by Ink-jet printing is the most regular and uniform. The power conversion efficiency of the best fabricated solar cell is 0.09%.
