X-ray detector overview. a Device schematic structure. b Performance comparison of current solid state X-ray detectors—(1)13, (2)10, (3)36, (4)37, (5)38, (7)8, (9)11, (11)3, (14)39, (15)40, (16)7, (17)41, (18)42, (19)43, (20)44, and (24)20 are direct detectors, (6)45, (8)46, (21)7,47 and (22)48 are inorganic detectors, and (10)12, (12)9, (13)25 and (23)49 are indirect detectors—with the technology developed in this work—(25) Bi2O3-40, (26) Bi2O3-80, (27) Bi2O3-40 and (28) Bi2O3-40. The operating voltage is given adjacent to each data point. The total attenuation coefficient values of carbon, selenium, methylammonium lead iodide (MAPbI3) and Bi2O3 are given as shaded areas showing the previous limits to detector technology based only on bulk attenuation processes. c An X-ray imager based on the hybrid X-ray detector and 70 kV X-ray image of a bolt taken using the X-ray imager
