    Metal oxide nanocrystalline thin films as buffer layers in organic/ hybrid solar cells
    (University of Western Cape, 2019) Bowers, Norman Mark; Muller, T.F.G.; Arendse, C.J.
    Without reverting to encapsulation, organic bulk - heterojunction solar cells can be protected from the oxidation of the highly reactive low work function cathode metal electrode, by the deposition of metal oxide buffer layers onto an indium-tin oxide (ITO) substrate. The zinc-oxide (ZnO) or titanium dioxide (TiO2) layer can serve as an electron collecting contact. In such a case the ordering of layer deposition is inverted from the traditional layer sequencing, using an additional effect of the metal oxide layer acting as a hole blocking contact
