Lastly, we extrapolate ion diffusion coefficients (∼10 –7 cm 2 s –1) and ionic conductivities (∼10 –7 S cm –1) from the Warburg mass (ion) diffusion response and show that, as the device degrades, there is an overall depletion of capacitive effects coupled with increased ion mobility. Furthermore, we show that a chemical double-layer capacitance buildup as a result of ion accumulation impacts the electronic properties of the device, likely by inducing either charge pinning or charge screening, depending on the direction of the ion-induced field. However, unlike observations in n-i-p devices, we found that there is a capacitive discharge leading to ion redistribution in the bulk at high forward biases.

We show that ion migration is predictably influenced by a low applied forward bias, characterized by an increased capacitance at the hole-transporting (HTM) and electron-transporting material (ETM) interfaces, as well as in bulk. Using electrochemical impedance spectroscopy (EIS) and equivalent circuit modeling, we elucidated various resistive and capacitive elements in the device. All ticket holders are welcome to attend the post show discussion.We studied ion transport in hybrid organic–inorganic perovskite p-i-n devices as a function of applied bias under device operating conditions. The four-show package starts at $99.Ĭurrent ticket holders may add the pre-show reception to their existing ticket for $10 per person. IllumiNation tickets include a ticket to the show, a pre-show reception, and a currated post-performance discussion.
