Our group has expertise in various coating techniques for emerging photovoltaic technologies (such as perovskite solar cells and modules) including blade and slot-die coating, screen printing or roll-to-roll deposition. Moreover, there is a wide expertise in device characterization and modelling, e.g. photoluminescence and electroluminescence imaging and mapping techniques or transient optoelectrical measurements. Fraunhofer ISE moreover is a global leader to perform calibrated, certified performance measurements of photovoltaic devices.
