Abstract
The present study is demonstrating the deposition of solution based nanostructured silver top electrode for inverted organic solar cells. The deposition of silver nanoparticles through hybrid electrohydrodynamic atomization (Hybrid-EHDA) is discussed in detail. The film thicknesses were varied with respect to spray times. The interface between the metal electrode and organic film was investigated using a focused ion beam analyzer. The sheet resistance of nanostructured silver film was reduced by increasing the film thickness. The lowest sheet resistance of silver film is ~0.07 Ω/sq with a film thickness of 2.6 µm. The power conversion efficiency of fabricated devices was found to be influenced by the sheet resistance of silver film. The maximum power conversion efficiency (~2.44%) was observed at 0.07 Ω/sq. Our results demonstrate that the Hybrid-EHDA will play a promising role in the fabrication of inverted organic solar cells using a solution based top electrode.
