Basic Performance of Single-Crystal Perovskite Photodetector

(A) I-V characteristics of the devices under 553 nm with different light intensities at X = 0 μm.

(B) The plot of photocurrent versus light intensity at V = 10 V (λ = 553 nm; X = 0 μm).

(C) Time response of the device illuminated with and without a 553-nm laser (22 μW; X = 0 μm) at a voltage of 10 V.

(D) The amplified sections of a 61–63.5 s range and 72–74 s range corresponding to light-off to light-on and light-on to light-off transitions from Figure 2C.
