Operando multidimensional spectroscopy reveals A-site-dependent carrier cooling in perovskite solar cells
Edoardo Amarotti, Luca Bolzonello, Qi Shi +6
Understanding how photogenerated carriers dissipate excess energy in operating perovskite solar cells is essential for connecting ultrafast photophysics with photovoltaic function…
Disorder-Induced Localization of Molecular Polaritons Despite Spectroscopic Strong Coupling
Amitav Sahu, Tönu Pullerits
Molecular polaritons are hybrid light--matter quasiparticles whose collective character is often associated with molecular excitations extending over many emitters. However, molecu…
Helicity-Resolved Spatiotemporal Mapping of Chiral Plexcitons in Helicoids
Jeong Hyun Han, Sankaran Ramesh, Jaeyeon Jo +10
Plasmon-exciton hybrids, or plexcitons, offer deeply subwavelength light-matter interactions with versatile pathways for energy redistribution. Incorporating chirality into such sy…
About carrier's self-trapping and dynamical Rashba splitting in the two-dimensional hybrid perovskite (BA)(MA)PbI
W. Qi, S. Ponzoni, G. Huitric +13
Time- and Angle-Resolved Photoelectron Spectroscopy (tr-ARPES) is employed to monitor photoexcited electrons in the two-dimensional hybrid perovskite (BA)(MA)PbI…
Phonon-Mediated Chirality Transfer from Organic Cation to Inorganic lattice in Hybrid Perovskites
Sankaran Ramesh, Prasenjit Mandal, Rafael Araujo +6
Two-dimensional hybrid metal halide perovskites combine strong spin-orbit coupling, soft lattice dynamics and molecular tunability, making them promising platforms for chiral optoe…
Photocurrent detected 2D spectroscopy via pulse shaper: insights and strategies for optimally untangling the nonlinear response
