Trace MA+ Accelerates the Degradation of Perovskite Solar Cells at Elevated Temperatures
We investigate how the A‐site cation influences the morphology and optoelectronic properties of perovskite films, and consequently, the operational stability of devices under continuous light illumination at elevated temperature. ABSTRACT Methylammonium (MA+) is the most widely adopted A‐site cation for high‐efficiency perovskite solar cells.

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

A chelating coordination strategy using ethylenediamine diacetate (EDDA) is introduced to regulate crystallization and passivate defects in Sn–Pb perovskite solar cells. Interfacial coordination at both buried and top surfaces suppresses Sn2+ oxidation, reduces defects, and enhances charge extraction, enabling over 23% efficiency with improved voltage,

This study investigates the effect of the chemical composition on the properties of A(BB’)(XX’)3$_3$ inorganic halide perovskites with density functional theory. By correlating distortion amplitudes with both composition and the Goldschmidt tolerance factor, we propose a pragmatic approach to designing more stable and efficient perovskites, advancing ...

Carbazole‐based self‐assembled monolayers (SAMs) have proven effective as HTLs in perovskite solar cells (PSCs). However, the energy alignment with narrow‐bandgap lead‐tin (Pb‐Sn) perovskites is suboptimal. Here, we design four phenoxazine/phenothiazine SAMs.
