Intensity-Modulated Photocurrent Spectroscopy and Its Application to Perovskite Solar Cells
(American Chemical Society, 2020-09-23)
Frequency domain techniques are useful tools to characterize processes occurring on different time scales in solar cells and solar fuel devices. Intensity-modulated photocurrent spectroscopy (IMPS) is one such technique ...
Interfacial Mechanism for Efficient Resistive Switching in Ruddlesden-Popper Perovskites for Non-volatile Memories
(American Chemical Society, 2020-01-16)
Ion migration, one origin of current–voltage hysteresis, is the bane of halide perovskite optoelectronics. Herein, we leverage this unwelcome trait to unlock new opportunities for resistive switching using layered ...
Surface-Functionalized Polystyrene Nanoparticles Alter the Transmembrane Potential via Ion-Selective Pores Maintaining Global Bilayer Integrity
(ACS Publications, 2022)
Although nanoplastics have well-known toxic effects toward the environment and living organisms, their molecular
toxicity mechanisms, including the nature of nanoparticle−cell membrane interactions, are still under ...
Combining Modulated Techniques for the Analysis of Photosensitive Devices
(Wiley-VCH GmbH, 2021-09-03)
Small-perturbation techniques such as impedance spectroscopy (IS), inten-sity-modulated photocurrent spectroscopy (IMPS), and intensity-modulated photovoltage spectroscopy (IMVS) are useful tools to characterize and model ...
A three-dimensional model to describe complete human corneal oxygenation during contact lens wear
(Wiley, 2022-10-10)
We perform a novel 3D study to quantify the corneal oxygen consumption and diffusion in each part of the cornea with different contact lens materials. The oxygen profile is calculated as a function of oxygen tension at the ...
Balanced change in crystal unit cell volume and strain leads to stable halide perovskite with high guanidinium content
(Royal Society of Chemistry, 2022)
Up-to-date studies propose that strain in halide perovskites is one of the key factors that determine
a device's efficiency and stability. Here, we show a systematic approach to characterize the
phenomenon in the standard ...
Femtosecond-laser-irradiation-induced structural organization and crystallinity of Bi2WO6
(Nature Research, 2020)
Controlling the structural organization and crystallinity of functional oxides is key to enhancing
their performance in technological applications. In this work, we report a strong enhancement of
the structural organization ...
New Views on Carrier Diffusion and Recombination by Combining Small Perturbation Techniques: Application to BiVO4 Photoelectrodes
(Wiley, 2022)
Impedance spectroscopy (IS), intensity-modulated photocurrent spectroscopy (IMPS), and intensity-modulated photovoltage spectroscopy (IMVS) are well-established powerful modulated techniques to characterize optoelectronic ...
Decoupling manufacturing from application in additive manufactured antimicrobial materials
(Royal Society of Chemistry, 2021-05-11)
3D printable materials based on polymeric ionic liquids (PILs)
capable of controlling the synthesis and stabilisation of silver
nanoparticles (AgNPs) and their synergistic antimicrobial activity
are reported. The ...
