Dye-sensitized and perovskite solar cells

Gerrit Boschloo's research group investigates fundamental aspects of dye-sensitized solar cells (DSC) and perovskite solar cells (PSC).  Both technologies offer the prospect of low-cost solar energy conversion, but need further research since the precise function of these complex systems is not well understood. In DSC, organic dye molecules are adsorbed onto nanostructured metal oxide electrodes, leading to solar cells that can have all the colors of the rainbow. By careful tuning of the molecular design of dye and redox mediator or hole conductor, highly efficient solar cells can be made. Since 2012, PSC with the hybrid organic-inorganic absorber material MAPbI3 is under investigation. PSC is the latest photovoltaic technology with reported record efficiencies up to 20%. Many aspects of PSC, such as stability, hysteresis, and ion conductivity need further investigation.
