Co-Doping Approach for Enhanced Electron Extraction to TiO<sub>2</sub> for Stable Inorganic Perovskite Solar Cells. [PDF]
Small SciTiO2 is highly relevant in photoelectrochemistry, (photo)catalysis, and sensor applications, where high conductivity is crucial. Herein, a co‐doping strategy for TiO2 using Nb(V) and Sn(IV) is developed, enhancing electron extraction from perovskite and improving solar cell efficiency and stability.

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.

Journal of Applied Ecology, Volume 60, Issue 9, Page 1752-1762, September 2023., 2023 Ground‐mounted solar photovoltaic developments have a significant negative effect on bat activity, and should be considered in appropriate planning legislation and policy. Solar photovoltaic developments should be screened in Environmental Impact Assessments for ecological impacts, and appropriate mitigation (e.g.

Discrete Donor–Acceptor Pair Transitions in CH3NH3PbI3 Perovskite Single Crystals
physica status solidi (RRL) – Rapid Research Letters, Volume 17, Issue 7, July 2023., 2023 Herein, the low‐temperature photoluminescence of high‐quality CH3NH3PbI3 perovskite single crystals is investigated. Important variations in shape and intensity of the defect emission are observed and are explained by donor–acceptor pair (DAP) recombination in presence of potential fluctuation.

The Saga of Water and Halide Perovskites: Evidence of Water in Methylammonium Lead Tri‐Iodide
Advanced Functional Materials, Volume 32, Issue 43, October 21, 2022., 2022 Direct evidence of release of H2O from bulk MAPbI3, under the conditions where the MAPbI3 crystal structure is intact and with an indication of a H2O gradient of MAPbI3.xH2O with x=1 at the surface to x=0 in the bulk. Abstract The environment humidity effects on performance of halide perovskites (HaPs), especially MAPbI3, are known. Nevertheless, it is

Self‐Healing and Light‐Soaking in MAPbI3: The Effect of H2O
Advanced Materials, Volume 34, Issue 35, September 1, 2022., 2022 The two‐photon‐induced photodamage and consequent self‐healing inside MAPbI3 single crystals are investigated. Two photobrightening and one photodarkening process are identified, which are connected to trap‐filling, methylamine‐chemistry, and the lead‐halide sublattice. H2O is found to strongly influence the overall photodamage and kinetics of the self‐

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.

Advanced Optical Materials, Volume 13, Issue 32, November 14, 2025.This work addresses a common issue in many double perovskites: their weak luminescence. Using the example of promising infrared‐bandgap mixed‐valence gold halide double perovskites, it demonstrates strong polar electron‐phonon coupling. Temperature‐dependent spectroscopy reveals that bright polarons are favored at low temperature, while a dark low ...
