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

open access: yesAdvanced 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

Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.
