Understanding halide segregation in metal halide perovskites through defect thermodynamics
Abrar Fahim Navid, Zeeshan Ahmad
Halide segregation in metal halide perovskites limits their bandgap tunability and hinders their adoption in tandem solar cells and light emitting diodes. Here, we reveal the therm…
Grain Boundaries in Ceramic Solid-State Lithium Metal Batteries: A Review
Md Salman Rabbi Limon, Abrar Fahim Navid, Curtis Wesley Duffee +1
It is now widely accepted that grain boundaries play a critical role in the performance and reliability of solid-state batteries with lithium metal anodes. Understanding and contro…
Constriction and contact impedance of ceramic solid electrolytes
Md Salman Rabbi Limon, Curtis Duffee, Zeeshan Ahmad
The development of solid-state batteries (SSBs) is hindered by degradation at solid-solid interfaces due to void formation and contact loss, resulting in increased impedance. Here,…
Modulation of Point Defect Properties Near Surfaces in Metal Halide Perovskites
Bilal Ahmad, Md Salman Rabbi Limon, Zeeshan Ahmad
It is now widely recognized that surface and interfacial defects exhibit distinct behavior compared to bulk defects in metal halide perovskites. However, the transition from bulk t…
