Tuning the Optical Properties of Cesium Lead Halide Perovskite Nanocrystals by Anion Exchange Reactions
Quinten A. Akkerman,Valerio D’Innocenzo,Sara Accornero,Alice Scarpellini,Annamaria Petrozza,Mirko Prato,Liberato Manna +6 more
TL;DR: It is demonstrated that, via controlled anion exchange reactions using a range of different halide precursors, this approach gives access to perovskite semiconductor NCs with both structural and optical qualities comparable to those of directly synthesized NCs.
Journal ArticleDOI
Excitons versus free charges in organo-lead tri-halide perovskites
Valerio D’Innocenzo,Valerio D’Innocenzo,Giulia Grancini,Marcelo J. P. Alcocer,Marcelo J. P. Alcocer,Ajay Ram Srimath Kandada,Samuel D. Stranks,Michael M. Lee,Guglielmo Lanzani,Guglielmo Lanzani,Henry J. Snaith,Annamaria Petrozza +11 more
TL;DR: Optical spectroscopy is used to estimate the exciton binding energy in the mixed-halide crystal to be in the range of 50 meV, and it is shown that such a value is consistent with almost full ionization of the excitonic population under photovoltaic cell operating conditions.
