Organic photovoltaic cells (OPVs) represent a promising alternative to high costly silicon-based solar cells. In comparison with these, OPVs exhibit relatively low energy conversion efficiency and suffer from unsatisfactory stability. The morphology of the organic (active) layer plays a fundamental role in what concerns efficiency enhancement and its structural stability is of paramount importance for the device lifetime. Here, we review our recent efforts to tailor film morphology in OPVs through nanostructuring and stabilizing the electron-donor polymer layer.
