X‐ray detectors are widely utilized in medical diagnostics and nondestructive product inspection. Halide perovskites are recently demonstrated as excellent candidates for direct X‐ray detection. However, it is still challenging to obtain high quality perovskites with millimeter‐thick over a large ar...
