Abstract
The fabrication of perovskite-polymer composites elevates the potential of perovskite-based radiation detectors. Combining the facile production of all-inorganic perovskite materials with the mechanical properties of a polymer can result in the convenient production of large-area, environmentally stable detectors. This work presents the fabrication and characterization of a novel hybrid material that has been created by mixing together the perovskite CsPbBr 3 with a polymer to produce a solid plastic composite. Test samples are polished pellets with metal contacts to enable direct detection via charge collection. IV-characterization data and photocurrent response data has been collected from a composite test device composed of ~8% perovskite material by weight. Bias sweeps have been performed and the dark current measured. X-ray illumination from a 70 kV source across a series of mA values demonstrates the clear linear response of the device over a range of dose-rates. Additionally, microCT and SEM imaging has been used to study the dispersion of CsPbBr 3 through the composite. This work lays the foundation for novel perovskite-polymer radiation detection devices through detector characterization and compositional analysis.
