We describe the fabrication and characterization of large-area active-matrix X-ray/photodetector array of high quality using organic photodiodes and organic transistors. All layers with the exception of the electrodes are solution processed. Because it is processed on a very thin plastic substrate of 25 mu;m thickness, the photodetector is only 100 mu;m thick. When combined with an 300-μm-thick X-ray scintillator, this gives a thin, low-weight and shatterproof X-ray detector of ca. 400 mu;m thickness. We demonstrate X-ray imaging under conditions that are used in medical applications. © 2013 Elsevier B.V.
