Spectroscopic Ellipsometry Characterization and Radiative Limit Modeling of Bismuth‐Based Perovskite‐Inspired Absorbers for Indoor Photovoltaics

Advanced Optical Materials, EarlyView.
This study determines the optical constants of two lead‐free perovskite‐inspired materials (PIMs), Cu2AgBiI6 and Cs3Bi2I6Br3, promising for indoor light conversion. The optical constants are applied to simulate photovoltaic device optics, and thereupon, revise the theoretical limits for photocurrent generation and power conversion efficiency, providing

Ultrabroadband Excitation of Hot Carriers in Plasmonic Nanorods Revealed by Two‐Dimensional Electronic Spectroscopy

Advanced Optical Materials, EarlyView.
This work dissects the ultrafast response of polydisperse plasmonic nanorods using two‐dimensional electronic spectroscopy, uniquely combining temporal and spectral resolution. Our ultrabroadband pulses cover both transverse and longitudinal nanorods’ resonances, revealing sub‐200‐fs dynamics and distinct broadening mechanisms.

Thickness Dependence of Linear and Nonlinear Optical Properties of Multilayer 3R‐MoS2

Advanced Optical Materials, EarlyView.
Thickness as a key design parameter for optimizing the nonlinear optical response of layered transition metal dichalcogenides (TMDs) materials is established. The demonstrated correlation between thickness, linear spectra, and harmonic generation efficiency provides a powerful framework for tailoring nonlinear performance.
