Fabrication and characterization of printed perovskite-based photodiodes

We fabricated the first perovskite-based photodiodes using one-step and two-step deposition with Spiro-OMeTAD as Hole Transport Material (HTM). Our photodiode show excellent rectification behavior, low dark currents under reverse bias and good dynamic properties evaluated with Bode and eye diagram. A frequency resolved noise analysis was performed in order to extract detectivity and optimal bias potential values.
