Effective Glycerol Carbonate Synthesis From Glycerol and Dimethyl Carbonate Over Rb‐Doped SrTiO3 Nanoparticles

ChemCatChem, Volume 18, Issue 6, 27 March 2026.
Alkali metal doping enhanced the catalytic performance of SrTiO3 for glycerol carbonate synthesis. Among the tested catalysts, the 10% Rb‐doped SrTiO3 exhibited the highest catalytic activity. This catalyst could be reused without substantial loss of activity and was applicable to various combinations of diols and alkyl carbonates.

Rapid Microwave Annealing of Perovskites: Effects on Device and Material Stability in High Humidity

EcoMat, Volume 8, Issue 3, March 2026.
This study demonstrates that microwave annealing significantly improves the stability of perovskite solar cells when exposed to high humidity conditions. Compared to traditional hot‐plate methods, microwave processing promotes the development of larger crystal grains, thereby obstructing moisture ingress and delaying degradation.

Vertically Oriented Single‐Layer Grains for a Highly Bifunctional Perovskite Photovoltaic Light‐Emitting Device

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The realization of bifunctional perovskite devices integrating photovoltaic (PV) and light‐emitting diode (LED) capabilities requires precisely controlled grain architectures to facilitate dual carrier transport pathways. In this work, sulfaguanidine (SG) molecules were introduced into the perovskite solution to reconstruct the crystallization

Exploring Wide‐Range Alkyl Bridge Length Variations in Polymer Semiconductors: From Pristine to Blend Films for High‐Mobility Stretchable TFTs

Small, Volume 22, Issue 13, 3 March 2026.
A side‐chain engineering strategy enables polymer semiconductors to achieve record‐high mobility and mechanical resilience in intrinsically stretchable transistors. By correlating crystallinity with charge transport and stretchability, this work establishes a predictive design rule.

Impact of Device Architecture on Proton Detection Efficiency in 2D Perovskite Thick Film Detectors

Small, Volume 22, Issue 15, 12 March 2026.
This work shows the role of device architecture in MeV proton detection with 2D perovskite thick (> 1 µm) films. A direct comparison between planar and stacked devices demonstrates that the stacked geometry achieves superior response by enabling more efficient charge collection and better exploitation of the active layer volume, ensuring stable and ...

Anion Component Engineering of Spontaneous Perovskite Passivators for Energy Alignment Modulations in Perovskite Solar Cells

Small, Volume 22, Issue 16, 17 March 2026.
n‐Octylammonium bis(fluorosulfonyl)imides (OA‐FSI, OA‐TFSI, and OA‐PFSI), used as additives for spiro‐OMeTAD hole‐transport materials (HTMs) in perovskite solar cells (PSCs), allow spontaneous perovskite passivation during HTM deposition. Anion component engineering of the OA‐bis(fluorosulfonyl)imides effectively modulate energy alignment in PSCs via ...

Reorientation‐Driven Degradation in Oriented Perovskite Films: Shifting Facet Engineering to Thermodynamic Stability

Small, Volume 22, Issue 14, 6 March 2026.
The role of crystallographic orientation in the thermal stability of narrow‐bandgap perovskite solar cells remains largely underexplored. In Sn–Pb mixed perovskite films, strong orientation can inherently compromise stability under prolonged thermal stress, triggering reorientation‐induced degradation through microstrain accumulation.

Controlling Green‐Solvent Processability via the Dipole Moment of Nonfullerene Acceptor in Green‐Light Wavelength‐Selective Organic Solar Cells

ChemSusChem, Volume 19, Issue 4, 25 February 2026.
For the environmentally friendly fabrication of green‐light wavelength‐selective organic solar cells (GLWS‐OSCs), a new nonfullerene acceptor, BTz‐TT‐FA, bearing a low dipole moment is designed and developed. GLWS‐OSCs based on poly(3‐hexylthiophene) (P3HT) and BTz‐TT‐FA showed enhanced photovoltaic performance under p‐xylene processing compared to ...
