Combinatorically Inkjet-Printed Metal Halide Perovskite Optoelectronic Devices

Beyond the use in home and office-based printers, inkjet printing has become a popular structuring and selective deposition technique in industry. Metal halide perovskites (MHP) have received great attention in recent years, predominantly due to the high performance of perovskite solar cells. Yet, the versatility of this material class has also allowed its use in light-emitting diodes and photo detectors. In all these device applications the tunability of the energy bandgap is of particular importance. In this contribution we will show the fabrication of combinatorically printed photodetector arrays, large area multi color light emitting devices, as well as inkjet printed solar cells.
