  • Optimized growth of stable hybrid perovskite materials for electromagnetic and particle radiation detection
    Patent number: 11952679
    Abstract: Inverse temperature crystallization processes are provided to produce perovskite single crystals (PSCs), as well as surface passivation techniques for producing stabilizing the PSCs in the bulk region. Stable hybrid perovskite material include a bulk region comprising a single crystal perovskite material having a first bandgap and a smooth perovskite surface layer having a second bandgap greater than the first bandgap. Devices for detection and energy conversion are also contemplated, including for spectroscopic photon and elementary particle detection, such as radiation detectors. Crystallization chambers for forming the PSCs are also provided.
    Type: Grant
