Effect of Preheating on Phase Distribution and Orientation of 2D Halide Perovskite for Indoor Photovoltaics

Energy Technology, Volume 14, Issue 3, March 2026.
The BA2MA3Pb4I13, where (BA is butylammonium, MA is methylammonium) quasi‐2D halide perovskites are identified as a promising material with a suitable bandgap of 1.9 eV for indoor light harvesting. A combination of lower thickness of 260 nm, better phase purity and greater (202) crystal orientation obtained from preheating, yielded a champion power ...

In Situ Growth of 2D Perovskite Nanocrystals to Induce β–Phase of PVDF for Piezoelectric Nanogenerators with Ultra‐High Output Voltage

Small, Volume 22, Issue 15, 12 March 2026.
In situ grown 2D perovskite nanocrystals embedded in PVDF enable flexible piezoelectric nanogenerators with greatly enhanced β‐phase content and a high d33∗${\mathrm{d}}_{33}^{\mathrm{*}}$ of 35.16 pm/V. The devices deliver up to 66.54 V, exhibit light‐enhanced piezoelectricity, and maintain durability over 12000 cycles, offering a stable energy source

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.
