The present disclosure provides a radiation detector, including a substrate, a pixel array formed on the substrate, a perovskite thick film formed on the pixel array and having a cubic crystal phase, a first electrode formed on the perovskite thick film and is opposite to the pixel array, and a readout circuit. The radiation detector has significantly reduced dark current density and high sensing sensitivity. The present disclosure also provides a method for preparing the perovskite thick film.

Perovskite thick film, preparation method thereof, and radiation detector comprising the same

Provided are a perovskite film and a manufacturing method thereof. The method includes the following steps. A perovskite precursor material is coated in a linear direction on a substrate with a temperature between 100&#xb0; C. and 200&#xb0; C., wherein a concentration of the perovskite precursor material is between 0.05 M and 1.5 M. An infrared light irradiation is performed on the perovskite precursor material to cure the perovskite precursor material to form a thin film including a compound represented by formula (1). The perovskite film has a single 2D phase structure or has a structure in which a 3D phase structure is mixed with a single 2D phase structure.(RNH)MAMX&#x2003;&#x2003;formula (1),

Perovskite film and manufacturing method thereof

Organic dyes and photoelectric conversion devices are provided. The Organic dye has the structure represented by formula (I), wherein, n is an integral of 2-11; the plurality of X is independent and elected from the group consisting of and combinations thereof; R, R, and Rcomprise hydrogen, halogen, Calkyl group, Calkoxy group, Cheteroalkyl group, Caryl group, Cheteroaryl group, Ccycloaliphatic group or Ccycloalkyl group, or Ris connected to Rto form a ring having 5-14 members; Rcomprise hydrogen, halogen, nitro group, amino group, Calkyl group, Calkoxy group, Csulfanyl group, Cheteroalkyl group, Caryl group, Cheteroaryl group, Ccycloaliphatic group or Ccycloalkyl group; and Z is hydrogen, alkali metal, or quaternary ammonium salt.
