The stability of a common interface used in organic photovoltaic cells, between the transparent electrode of Indium Tin Oxide (ITO) and the polymer buffer layer (PEDOT:PSS) is strongly influenced by the presence of humidity during processing. This leads to significant migration of indium and tin species into the PEDOT:PSS layer.
