Fabrication and characterization of mesoscopic Perovskite photodiodes
Mesoscopic photodiodes were fabricated with hybrid organic/inorganic perovskite as absorber layer and Spiro-OMeTAD as Hole Transport Layer. The perovskite layer was grown using a two-step deposition technique. Our photodiode in addition to a good rectification behavior (3 orders of magnitude, range -1V to 1V) shows a small noise current (< 1pA/(Hz)1/2), a high responsivity value (0.35 A/W) at 500 nanometers and a good spectral response in the entire visible range. The Bode analysis shows a bandwidth of 108 KHz.
