摘要
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 (three orders of magnitude, range -1 to 1 V) shows a small noise current (< 1 pA/(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.
