Interfacial Engineering by Metallic Ions and Organic Ammonium Ligand Passivation for Perovskite Solar Cells

Advanced Science, Volume 13, Issue 37, 3 July 2026.
A synergistic approach using phenethylammonium iodide (PEAI) and antimony iodide (SbI3) enhances the operational stabilities of perovskite solar cells by providing p‐type doping effect, suitable band energy alignment, reduced defect density, and minimized surface ion vacancies in the perovskite films.

Strong Nonradiative Recombination Induced by Pronounced Lone‐Pair Electron Expression Following Deprotonation in Aziridinium Lead Iodide Perovskites

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
The transition from linear to cyclic organic cations promotes deprotonation and activates VH(N) defects with pronounced lone‐pair electron activity, thereby inducing severe local distortions and highly efficient nonradiative recombination centers. This work unveils a direct structure–defect–performance correlation and proposes design strategies for the

Environmentally Friendly R2R Process for Flexible Perovskite Solar Cells via DMF‐Free Cosolvent Ink

EcoMat, Volume 8, Issue 7, July 2026.
A DMF‐free two‐step slot‐die coating process for roll‐to‐roll fabrication of perovskite solar cells is demonstrated using a DMSO:ACN cosolvent system. The process enables controlled porous PbI2 formation and efficient FAI conversion, resulting in high‐quality perovskite films with 15.84% efficiency on flexible substrates and offering a scalable ...

Electric Field‐Induced Dark Current Steering in MAPbI3/Nb2CTx Photodetector Toward Weak‐Light Single‐Pixel Imaging

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT In conventional photoconductive detectors, the shared collection path for dark current and photocurrent imposes a fundamental compromise between noise suppression and signal responsivity. To break this trade‐off, we introduce a device architecture featuring a strategically integrated third electrode within a MAPbI3/Nb2CTx heterostructure. This

Two-Dimensional Perovskites with Alternating Diammonium and Methylammonium Cations in the Interlayer Space for Stable Light-Emitting Diodes

The Journal of Physical Chemistry Letters
Metal halide perovskites constitute a promising area of research for application in light-emitting diodes (LEDs), given the successful demonstration of high external quantum efficiency (EQE) devices across the visible to the near-infrared window. Nevertheless, the ionic crystal structure, significantly impacted by internal defects and ionic migration ...

Molecular Passivation with 2‐Aminobenzothiazole Enables Efficient and Stable Ruddlesden–Popper Tin Perovskite Solar Cells

Solar RRL, Volume 10, Issue 11, 15 June 2026.
Using 2‐aminobenzothiazole additive in quasi‐two‐dimensional tin perovskite improved energy‐level alignment of the perovskite layer to match that of other charge transport layers leading to an improved solar cell performance. The additive also inhibitted iodine ion migration and oxidating leading to better solar cell stability.
