Research Interests

My research is concerned with nanostructured electrodes for organic photovoltaics. I fabricate transparent highly conductive nanostructured silver / ITO electrodes by template-assisted electrochemical deposition. These metal nanostructures will be characterized by conductive AFM and UV-Vis to optimize the conductivity and transparency. It is assumed that their application in organic solar cells will enhance the charge collection efficiency through these high conducting transport channels. This should ultimately lead to higher efficiencies.
