An X-ray detector, particularly a pixelated flat panel X-Ray detector using semiconducting perovskites as direct converting layer, has a top electrode, a photoactive layer containing at least one perovskite, and a bottom electrode, wherein the X-ray detector additionally has an electron blocking interlayer and/or a hole blocking interlayer containing an adhesion promoting additive, which can be one or more of saccharides and derivatives thereof, amino resins, epoxy resins, natural resins, and acrylic based adhesives.

The present disclosure relates to coated particles. The teachings thereof may be embodied in coated particles, a method for their production, and the use of the coated particles in X-ray detectors, gamma detectors, UV detectors, or solar cells. For example, some embodiments include particles comprising: perovskite crystals of the type ABXor ABX; wherein A comprises at least one monovalent, divalent, or trivalent element from the fourth or a higher period in the periodic table or mixtures thereof; B comprises a monovalent cation, the volumetric parameter of which is sufficient, with the respective element A, for perovskite lattice formation; and X is selected from the group consisting of halides and pseudohalides, and mixtures thereof; and a coating of at least one semiconductor material surrounding a nucleus comprising the perovskite crystals.

Coating made of a semiconductor material

The present disclosure relates to a detection layer on a substrate. For example, a detection layer may include perovskite crystals of the type ABXand/or ABX. A may include at least one monovalent, divalent or trivalent element from the fourth or a higher period in the periodic table and/or mixtures thereof. B may include a monovalent cation, the volumetric parameter of which is sufficient, with the respective element A, for perovskite lattice formation. X may be selected from the group consisting of anions of halides and pseudohalides. The layer may have a thickness of at least 10 &#x3bc;m.
