High‐quality CH 3 NH 3 PbI 3 single crystals are synthesized with desired intrinsic carrier dynamics revealed by time‐resolved photoluminescence spectroscopy and Hall effect measurement. Quantitative anisotropy of electron/hole mobility in CH 3 NH 3 PbI 3 single crystal is unveiled with a double diode configuration and anisotropic photon illumination. With intentional optical doping, the switching dynamics of the double diode photodetectors is regulated.
