Investigation of Tin Oxide Atomic Layer Deposition on the Performance of Evaporated Perovskite Solar Cells

Small, EarlyView.
Impact of co‐reactants and their doses utilized during the atomic layer deposition of SnOx on perovskite/C60 structures on the performance of p‐i‐n perovskite solar cells. ABSTRACT Although tin oxide (SnOx) layers grown using atomic layer deposition (ALD) are routinely employed in p‐i‐n perovskite solar cells (PSCs), the correlation between ALD process

Direct Synthesis of Short‐Chain Alkylammonium Capped FAPbI3 Perovskite Nanocubes for High‐Efficiency Solar Cells

Small, EarlyView.
Direct injection synthesis with short‐chain decylammonium iodide produces uniform FAPbI3 perovskite nanocubes through isotropic growth and surface passivation. The resulting films show reduced defect‐mediated recombination, improved phase stability, and efficient charge transport.

Ultrafast Coherent Phonon Dynamics in GeTe and GeSe: Contrasting Metavalent and Covalent Bonding

Small, EarlyView.
Ultrafast laser measurements reveal the differences in the optical response of atomic vibrations in GeTe and GeSe thin films. While crystalline GeTe exhibits strong, highly excitation‐sensitive coherent vibrations linked to metavalent bonding, covalently bonded GeSe shows weak or absent coherent phonons.

Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This article reviews the fundamental consequences of strong correlations on excitations and elementary steps of energy conversion leading to new opportunities to control energy conversion. Examples include friction at surfaces, thermal transport, and photovoltaic energy conversion.

Toward On‐Chip Nascent All‐van‐der‐Waals Polarization Optical Elements for Nanoscale Photonic Applications

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
Twisted ReSe2/α−MoO3 van der Waals heterostructures pave the way towards next‐generation polarization nanophotonic applications, where combining two biaxial layers—a triclinic source of linearly polarized emission and an orthorhombic polarization‐conversion slab—establishes a practical route for fully integrated on‐chip all‐van der Waals polarization ...
