Figure 2: Performance of hybrid perovskite photodetectors.
From: Solution-processed hybrid perovskite photodetectors with high detectivity
(a) Current density–voltage curves of photodetectors with and without the hole-blocking layer. PD1, without hole-blocking layers; PD2, with BCP as the hole-blocking layer; and PD3, with PFN as the hole-blocking layer. (b) External quantum efficiency and detectivity of the hybrid perovskite photodetector at different wavelength. The detectivity of a single-crystalline silicon diode (purple triangle) is shown for comparison.
