S Concentrating Table For Perovskite Low Noise

If the shot noise is the main contribution to the dark current I dark it can be simplified as R2qI dark 12 43 It is worth noting that the noise is independent of the frequency from the low frequency of 1 Hz to a high frequency of 10 5 Hz indicating that white noise is dominant rather than 1f noise Fig S3 18
