PROCEED develops new hybrid perovskite materials for the next generation of light detectors, -emissive and adaptive devices. In addition to photovoltaic energy have hybrid perovskites have a high application potential, for example in X-ray detectors and lasers. To this to realize its potential, the chemical and structural flexibility of perovskites will be exploited to take the material architecture to the next level of complexity and this through of a strategic based on variation in composition, doping and ligand chemistry, implementation of new hybrid perovskites with different dimensionality (2D, 3D), structures (nanoplates, thin films, thick layers and single crystals) and controlled morphology (crystallinity, uniformity), and their integration into advanced device structures. This makes one order magnitude to improve the material stability, as well as a sharp increase in the respective performance parameters (sensitivity to X-ray detectors, gain to lasers and conversion efficiency for solar cells), and this at lower or comparable production costs.
