A layer with a thickness of 192 nm annealed at 100 \u00b0C showed higher absorption, higher crystallinity, and lower surface roughness than did perovskite layers made under different conditions. In the indirect X-ray detector, a scintillator coupled with the detector to convert X-ray photons to visible photons, and the converted photons were absorbed by the active layer to generate charge carriers. The detector with the optimized MAPbI3 (192 nm thick and 100 \u00b0C annealing condition) active layer was coupled with a CsI(Tl) scintillator which consisted of 400 \u03bcm thick CsI and 0.5 mm thick Al, and achieved the highest sensitivity, i.e., 2.84 mA\/Gy\u00b7cm2. In addition, the highest short-circuit current density (JSC), i.e., 18.78 mA\/cm2, and the highest mobility, i.e., 2.83 \u00d7 10\u22124 cm2\/V\u00b7s, were obtained from the same detector without the CsI(Tl) scintillator.<\/jats:p>","DOI":"10.3390\/s20236872","type":"journal-article","created":{"date-parts":[[2020,12,1]],"date-time":"2020-12-01T13:08:51Z","timestamp":1606828131000},"page":"6872","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Characteristics of a Hybrid Detector Combined with a Perovskite Active Layer for Indirect X-ray Detection"],"prefix":"10.3390","volume":"20","author":[{"given":"Hailiang","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Electronic and Electrical Engineering, Dankook University, Gyeonggi-do 16890, Korea"}]},{"given":"Jehoon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Electronic and Electrical Engineering, Dankook University, Gyeonggi-do 16890, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1276-0440","authenticated-orcid":false,"given":"Jungwon","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Electronic and Electrical Engineering, Dankook University, Gyeonggi-do 16890, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7497","DOI":"10.1038\/ncomms8497","article-title":"Ionic transport in hybrid lead iodide perovskite solar cells","volume":"6","author":"Eames","year":"2015","journal-title":"Nat.
