(a) Noise current of photodetectors based on MAPbBr₃ and MAPbI₃ TSCs at 0-V bias voltage. (b) External quantum efficiency (EQE) and responsivity spectra of photodetectors based on MAPbBr₃ and MAPbI₃ TSCs. (c) Specific detectivity (D^*) of devices based on MAPbBr₃ and MAPbI₃ TSCs measured at 0-V bias and 8 Hz. (d) The current output of the MAPbBr₃ TSC device to green light with intensities of 0.35, 3.5, and 35 pW·cm⁻² (from Ref. [38]).
