Extended Data Fig. 8

Measurements were taken with the spectral analyzer SR770, and the low-noise current amplifier (Femto DLPCA-200) at ×1011 amplification coefficient for different test samples with no external bias voltage applied. It is seen that the noise for MAPbI3 SC (of 6 MΩ internal resistance) is just slightly higher than the thermal noise for the 10 MΩ resistors. For CdZnTe SC (of 10 GΩ internal resistance), the noise is limited by the amplifier.
