Figure 3: Photodetector based on ISC film.
From: Planar-integrated single-crystalline perovskite photodetectors

(a) Three-dimensional illustration of the photodetector: the MAPbBr3 ISC perovskite layer (orange) is deposited on top of the ITO contacts (light blue). The detector lay on a glass substrate (transparent grey). (b) Energy diagram of the photodetector. (c) Current–voltage characteristic measured in dark condition and (d) under different light power illumination, the colour bar is logarithmic.
