Binder chemistry sets the interfacial balance constant in CsPbBr nanocrystal supercapacitor electrodes
Arun Kumar, Monojit Bag
Previous work on lead-free tin halide perovskites showed that the binder instead sets the electrolyte concentration at which capacitance is maximised, following the relationship $1…
Sodium Incorporation in CsPbBrI Nanocrystal Electrodes: Lattice Contraction and the Suppression of Field-Driven Iodine Expulsion
Arun Kumar, Monojit Bag
Mixed-halide perovskite nanocrystal electrodes fail in supercapacitors through field-driven halide segregation. In undoped , this appears as a capacitance that…
Unraveling the Roles of Shallow, Deep and Auger Trapping in Charge Carrier Recombination in Triple-Cation Perovskites
Jitendra Kumar, Thomas Kirchartz, Alexandr Marunchenko +7
Understanding charge-carrier recombination in metal halide perovskites is essential for accurately identifying the factors limiting solar cell efficiency, yet it remains challengin…
Studies of long-lived photogenerated carriers in low band gap polymer photodiodes
M. Bag, K. S. Narayan
Defects in low-bandgap polymer based photodetectors play a critical role in determining switching characteristics in the near infra-red spectral-regime relevant to communication wa…
