Stabilization of Black FAPbI3 Perovskite by Interaction with the Surface of the Polymorphic Phase α-PbO
(Wiley-VCH GmbH, 2023-02-03)
The black phase of formamidinium lead iodide, FAPbI3, is optically active and promising for optoelectronics applications. However, it is difficult to synthesize and stabilize at room temperature since it thermodynamically ...
Inductive and capacitive hysteresis of current-voltage curves: unified structural dynamics in solar energy devices, memristors, ionic transistors, and bioelectronics
(American Physical Society, 2024-01-08)
Hysteresis observed in the current-voltage curves of both electronic and ionic devices is a phenomenon where the curve's shape is altered on the basis of the measurement speed. This effect is driven by internal processes ...
Enhancing the Electronic Properties and Stability of High-EfficiencyTin-Lead Mixed Halide Perovskite Solar Cells via DopingEngineering
(American Chemical Society, 2022-03-31)
Overcoming Voc loss to increase the efficiency of perovskite solar cells (PSCs) has been aggressively studied. In this work, we introduce and compare rubidium iodide (RbI) and potassium iodide (KI) alkali metal halides ...
Large grain size with reduced non-radiative recombination in potassium incorporated methylammonium-free perovskite solar cells
(Elsevier, 2022-12-31)
Organic–inorganic hybrid halide perovskites are widely considered to be one the most
promising material in photovoltaic technology, the use of this semiconductor as absorbent
layer in solar cells has attracted considerable ...
Vitamins as Active Agents for Highly Emissive and Stable Nanostructured Halide Perovskite Inks and 3D Composites Fabricated by Additive Manufacturing
(Wiley, 2022)
The use of non-toxic and low-cost vitamins like α-tocopherol (α-TCP, vitamin E) to improve the photophysical properties and stability of perovskite nanocrystals (PNCs), through post-synthetic ligand surface passivation, ...
Unusual Spectrally Reproducible and High Q-Factor Random Lasing in Polycrystalline Tin Perovskite Films
(Wiley, 2022)
An unusual spectrally reproducible near-IR random lasing (RL) with no fluctuation of lasing peak wavelength is disclosed in polycrystalline films of formamidinium tin triiodide perovskite, which have been chemically ...
