Entering the Strong Coupling Regime in Conventional Organic Solar Cells

Advanced Functional Materials, Volume 36, Issue 8, 26 January 2026.
Organic solar cells convert light into fossil‐free energy, yet they still cannot compete with their silicon counterparts. Strong exciton‐photon coupling can ameliorate some properties of organic solar cells, but it requires additional mirrors that diminish light absorbance. Here, mirror‐free strong exciton‐photon coupling is implemented in conventional

THz‐Driven Coherent Phonon Fingerprints of Hidden Symmetry Breaking in 2D Layered Hybrid Perovskites

Advanced Materials, Volume 38, Issue 4, 16 January 2026.
Intense THz pulses are employed to drive coherent phonons in 2D Ruddlesden‐Popper hybrid metal‐halide perovskites (HOIPs) from the (PEA)2(MA)n‐1PbnI3n+1 family, revealing mode‐selective spectroscopic signatures of inversion symmetry breaking in those nominally centrosymmetric materials. These findings provide a handle to decode nonlinear phonon driving

Tailoring Optical and Vibrational Properties by Bond Confinement: The Case of Metavalent Chalcogenide and Pnictogen Thin Films

Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
This perspective explores how intrinsic confinement effects in metavalent chalcogenide and pnictogen thin films alter optical and vibrational properties. By comparing thickness‐dependent effects across prototypical systems, this work highlights the role of unconventional bonding in shaping coherent phonon dynamics and dielectric functions, offering new

Dual‐Emission Switching in a Mn(II)‐Based Hybrid Bromide via Water Coordination: Synthesis, Structure, and Processing

Advanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
This study reports the synthesis, structure, and optical properties of (pr‐ted)2[MnBr4], a luminescent manganese (II) hybrid halide. It shows green emission under UV and transforms into a red‐emitting hydrated phase with humidity, reversible by heat or vacuum. Structural, photophysical, and theoretical analyses confirm the mechanism.

Mid‐Infrared Intersubband Transitions in p‐Type SiGe Parabolic Quantum Wells

Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
The design, growth, and characterization of hole‐doped Ge‐rich SiGe parabolic quantum wells exhibiting mid‐infrared intersubband transitions are reported. Structural analyses confirm the parabolic compositional profile, while optical spectroscopy supported by tight‐binding simulations demonstrates strong and temperature‐stable absorption up to room ...

Brillouin Microscopy of Breast tumor Spheroids On‐a‐Chip: Mechanical and Transcriptional Responses to Microfluidic‐Induced Rapid Deformations

Advanced Science, Volume 13, Issue 4, 19 January 2026.
Brillouin‐Raman Microspectroscopy on‐a‐Chip (BRmS) enables real‐time analysis of breast tumor spheroids in microfluidic channels. Following cyclical deformations, MCF10.DCIS.com spheroids are captured in recovery traps and imaged with BRmS. The applied deformations trigger a stiffening response marked by increased frequency shifts, elevation of the ...
