(color online) Device performance of single-crystalline perovskite photodetectors. (a) Dark current and photocurrent under different illumination powers of 1D perovskite arrays. The inset shows logarithmic I–V curves in the dark and under illumination with a power of 2.82 nW. (b) Photocurrent and responsivity of device under different incident powers (from Ref. [19]).
