High intrinsic detection efficiency is as decisive as high energy resolution. Scaling up detector volume has presented great challenges, preventing perovskite semiconductors from reaching sufficient detection efficiency. We report a hole-only virtual-Frisch-grid CsPbBr 3 detector up to 2.2 cm thick...
