Polymeric ionic liquid-based formulations for the fabrication of highly stable perovskite nanocrystal composites for photocatalytic applications
(Royal Society of Chemistry, 2023-02-09)
Halide perovskite nanocrystals (PNCs) have emerged as potential visible-light photocatalysts because of their outstanding intrinsic properties, including high absorption coefficient and tolerance to defects, which reduces ...
Current Challenges in the Development of Quantum Dot Sensitized Solar Cells
(Wiley, 2020-07)
Quantum dot sensitized solar cells (QDSSCs) have experienced a continuous performance growth in the past years presenting a photoconversion efficiency > 13%. QDSSCs constitute a smart approach to take advantage of the ...
Introducing Ion Mobility Mass Spectrometry to Identify Site-Selective C–H Bond Activation in N-Heterocyclic Carbene Metal Complexes
(American Chemical Society, 2022-11-14)
The activation of C−H bonds in a selective manner
still constitutes a major challenge from a synthetic point of view;
thus, it remains an active area of fundamental and applied research.
Herein, we introduce ion mobility ...
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 ...
Suppressing Nonradiative Recombination in Lead–Tin Perovskite Solar Cells through Bulk and Surface Passivation to Reduce Open Circuit Voltage Losses
(American Chemical Society, 2022-10-14)
Lead–Tin perovskite solar cells (Pb/Sn PSCs) are limited by the intrinsic instability of Sn(II), which tends to oxidize forming Sn vacancies in perovskite films. Herein, a Lewis base β-guanidinopropionic acid (GUA) and ...
Identification of Systemic Sclerosis through Machine Learning Algorithms and Gene Expression
(MDPI, 2022)
Systemic sclerosis (SSc) is an autoimmune, chronic disease that remains not well understood.
It is believed that the cause of the illness is a combination of genetic and environmental factors. The
evolution of the illness ...
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 ...
Unlocking a (Pseudo)-Mechanically Interlocked Molecule with a Coronene “Shoehorn”
