Electrochemical reactions under reverse bias create additional mobile ions that enable hole tunneling in metal halide perovskite diodes
Kell Fremouw, Ryan A. DeCrescent, Xianfu Zhang +11
Gradual reverse-bias breakdown in metal-halide perovskite diodes and solar cells is thought to originate from hole tunneling through steep bands in an ionic depletion region near t…
Degradation Dynamics of Perovskite Solar Cells Under Fixed Reverse Current Injection
Fangyuan Jiang, Haruka Koizumi, Hannah Contreras +8
Previous studies of reverse-bias stability in perovskite solar cells have focused primarily on voltage controlled reverse-bias tests. Here we instead present an investigation of pe…
Deposition-Dependent Coverage and Performance of Phosphonic Acid Interface Modifiers in Halide Perovskite Optoelectronics
Hannah Contreras, Aidan O'Brien, Margherita Taddei +10
In this work, we study the effect of various deposition methods for phosphonic acid interface modifiers commonly pursued as self-assembled monolayers in high-performance metal hali…
Kinetic Suppression of Photoinduced Halide Migration in Wide Bandgap Perovskites via Surface Passivation
Farhad Akrami, Fangyuan Jiang, Rajiv Giridharagopal +1
In this work, we study the kinetics of photoinduced halide migration in FACsPb(IBr) wide (~1.69 eV) bandgap perovskites and show halide migratio…
