Modeling Thin Film Solar Cells: From Organic to Perovskite

open access: yesAdvanced Science, 2020
Device model simulation is one of the primary tools for modeling thin film solar cells from organic materials to organic–inorganic perovskite materials. By directly connecting the current density–voltage (J–V) curves to the underlying device physics, it ...

Substrate-free generation of photosensitizer radical-ion pairs enables multipath photoredox for hypoxia-tolerant photodynamic therapy

open access: yesLight: Science & Applications
Photodynamic therapy (PDT) is fundamentally limited by inefficient conversion of photoexcited energy into reactive oxygen species (ROS), especially in hypoxic pathological tissues.

Photoisomeric Molecule-Mediated Ion Anchoring and UV Resistance in Metal Halide Perovskites

open access: yesResearch
Halide perovskites are novel photovoltaic materials with soft ionic lattice that are continuously exposed to sunlight during operation. High-energy ultraviolet (UV) irradiation will cause halide ion oxidation within the perovskite layer, accelerating ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Swelling-induced strain-isolation for stretchable and breathable integrated electronics

open access: yesNature Communications
Wearable electronics hold great promise for health management and chronic disease monitoring, yet their widespread applications are limited by insufficient stretchability, breathability, and mechano-electrical stability.
