Molecular Materials

The research is dedicated to the preparation, characterization and optimization of organic and organic/inorganic hybrid materials as new electrodes. The work aims at devices for photovoltaic cells, organic field-effect transistors or electrochromic applications. Films are prepared by physical vapor deposition or low-temperature solution-based methods. The group recently established ultrathin conductive layers for organic field-effect transistors, fast-switching organic electrochromic layers, dye-sensitized electrodes sustainably processed at low temperature and based on aqueous solutions, lead-free and stabilized organic-inorganic hybrid perovskite layers and revealed details of charge injection and recombination in dye-sensitized solar cells and of persistent polarization effects in hybrid organic/inorganic perovskite layers.
