Semitransparent organic solar cells are often considered as a unique stand-alone mark of organic photovoltaics in broad research field of optical technologies. Metal oxides as transparent electrodes, charge carrier extraction layers or protection for sensitive organic components play an important role for their realization.

Nowadays, the fact that the metal oxides are mostly prepared by vacuum evaporation impedes their convenient application in continuous roll-to-roll production technology based on liquid-phase-processing. The intention affirmed here should essentially contribute to handling of such issues. Specifically, a deposition technique for functional metal oxide layers from solved metal-organic precursors at low processing temperatures should be studied. In case of success, based on the results of this work fully solution-processed semitransparent organic solar cells could be possibly manufactured.

In addition to the electronic properties of the solution processed metal oxides, their functionality as a permeation barrier to oxygen and moisture and their capability to replace expensive encapsulation techniques should be studied.
