Degradation and Self‐Healing of FAPbBr3 Perovskite under Soft‐X‐Ray Irradiation

Small Methods, Volume 7, Issue 9, September 20, 2023., 2023
The optoelectronic properties of formamidinium lead tri‐bromide (FAPbBr3) films are monitored under synchrotron‐generated X‐rays by photoemission spectroscopy and micro‐photoluminescence. Initially, material degradation manifests with stoichiometric changes and quenching of photoluminescence emission.

The Role of Interfacial Energetics and Defects on The Efficiency of Tin Perovskite Solar Cells

Small, Volume 22, Issue 49, 1 September 2026.
ABSTRACT Tin perovskites are emerging as a sustainable alternative to lead‐based photovoltaics, yet their efficiency remains limited by energy‐level mismatch and intrinsic instability from tin oxidation. Progress is further hindered by inconsistent electrical behavior, obscuring the true bottlenecks of device performance.

Ab Initio Investigation of MgXe, Its Cation Mg+Xe and Clusters Mg+Xen: Electronic Structure, Spectroscopic Properties, and Temperature‐Dependent Absorption Spectra

International Journal of Quantum Chemistry, Volume 126, Issue 13, July 5, 2026.
Accurate potential energy curves, spectroscopic constants, and transition dipole moments were determined for the Mg+Xe and MgXe complexes. Spin–orbit effects were explicitly included for the Mg+Xe ionic system. Monte Carlo simulations were employed to investigate Mg+Xen clusters, and the temperature dependence of their absorption spectra was analyzed ...

Influence of the Chemical Composition on the Perovskites Anharmonicity: Toward a Stable Inorganic Perovskite

Solar RRL, Volume 10, Issue 6, 29 March 2026.
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 ...

Physics‐Based Machine Learning Electroluminescence Models for Fast yet Accurate Solar Cell Characterization

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 1, Page 116-131, January 2026.
Machine learning (ML) enables fast and reliable prediction of series resistance and dark saturation current maps from voltage‐dependent electroluminescence of silicon solar cells. Two ML algorithms, a multilayer perceptron (MLP) and a modified U‐NET (mU‐NET), are analyzed. They are compared to nonlinear least squares fitting to assess their performance.
