Summary
The MPL develops photoactive materials with partly new methods. Nanostructured silicon and III-nitrides show great potential for thin-film photovoltaics. For the first time, it was possible to produce large-area regular silicon nanowires from 6 µm thin polycrystalline films on glass. Progress has been made in functionalization and contacting with organic molecules, transparent conductive oxides and graphen. Hybrid polymer(PEDOT:PSS)-silicon-interfaces show remarkable characteristics and allow solar cells with open circuit voltage exceeding 600 meV.
