Abstract: A radiation detector includes a substrate including a charge collection electrode, a radiation absorption layer disposed on one side with respect to the substrate and including perovskite structure particles and a binder resin; and a voltage application electrode disposed on the one side with respect to the radiation absorption layer, a bias voltage being applied to the voltage application electrode so that a potential difference is generated between the voltage application electrode and the charge collection electrode.

Abstract: A radiation detector includes a substrate including a first electrode portion, a radiation absorption layer disposed on one side with respect to the substrate and configured of a plurality of perovskite crystals, and a second electrode portion disposed on the one side with respect to the radiation absorption layer and being opposite to the first electrode portion with the radiation absorption layer interposed therebetween. Each of the plurality of perovskite crystals is formed to extend with a first direction in which the first electrode portion and the second electrode portion are opposite to each other as a longitudinal direction in a region between the first electrode portion and the second electrode portion in the radiation absorption layer.

Abstract: A radiation detector includes a substrate having a plurality of charge collection electrodes, a radiation absorption layer disposed on one side with respect to the substrate and formed of a perovskite material, a voltage application electrode disposed on the one side with respect to the radiation absorption layer, a bias voltage being applied to the voltage application electrode so that a potential difference is generated between the voltage application electrode and each of the plurality of charge collection electrodes, and a protective member disposed on the one side with respect to the substrate and being in contact with at least portions opposite to each other in a side surface of the radiation absorption layer.
