Toward Reliable Metal Halide Perovskite FETs: From Electronic Structure and Device Physics to Stability and Performance Engineering

open access: yesAdvanced Electronic Materials, Volume 12, Issue 7, 6 April 2026.
Metal halide perovskite field‐effect transistors (PeFETs) offer great promise for flexible, low‐cost, and high‐performance due to their excellent charge carrier properties. However, challenges like ion migration, hysteresis, and instability limit their performance.

Stability of Perovskite Indoor Photovoltaics: A Focused Review and a Call for Standardized Stability Reporting

open access: yesAdvanced Energy Materials, Volume 16, Issue 14, 8 April 2026.
While perovskite solar cells have been widely studied, including their stability, perovskite indoor photovoltaics (IPVs) have only recently emerged. Nevertheless, more studies are appearing in the literature. The systematic stability study of IPVs is crucial, particularly given the inconsistencies in reported methodologies and results, which call for ...

Operational stability of mixed Sn–Pb perovskite solar cells: Mechanisms, mitigation strategies, and perspectives

open access: yesBulletin of the Korean Chemical Society, Volume 47, Issue 4, Page 416-428, April 2026.
This review consolidates mechanisms and solutions for mixed Sn–Pb perovskite solar cells. It identifies Sn2+ oxidation, iodine generation, and interfacial defects as primary instabilities. It discusses progress in additives, interface passivation, alternative hole transport layers, and solvent engineering as well as future directions for achieving long‐

Context‐Dependent Chemoselectivity of Aromatic C‐Methyltransferases

open access: yesChemBioChem, Volume 27, Issue 8, April 2026.
Chemoselectivity is context‐dependent: The SAM‐dependent C‐MTs SfmM2 and NapB5 from streptomycetes catalyze the C‐ and/or O‐dimethylation of aromatic substrates, including l‐tyrosine and flavonoids. C‐methylation activity requires precise substrate recognition and positioning to ensure proximity between the target carbon nucleophile and the methyl ...

Spatial transcriptomic analysis of the immune landscape following NBUVB treatment of vitiligo skin

open access: yesClinical &Translational Immunology, Volume 15, Issue 4, 2026.
Narrow‐band UVB (NBUVB) phototherapy is an effective, non‐invasive treatment for vitiligo vulgaris, but its impact on dermal T cells—the key drivers of disease—remains unclear. Using spatial transcriptomics, this study reveals that NBUVB phototherapy significantly remodels the immune landscape in the skin of Indian vitiligo patients.
