PROJECT TITLE :
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 employing a 2-step deposition technique. Our photodiode additionally to a good rectification behavior (three orders of magnitude, range -one to 1 V) shows a small noise current (<; one pA/(Hz)1/2), a high responsivity worth (0.35 A/W) at 500 nanometers, and a good spectral response in the complete visible range. The Bode analysis shows a bandwidth of 108 KHz.
