Dynamic Instability and Time Domain Response of a Model Halide Perovskite Memristor for Artificial Neurons
(American Chemical Society, 2022-04-22)
Memristors are candidate devices for constructing artificial neurons, synapses, and computational networks for brainlike information processing and sensory-motor autonomous systems. However, the dynamics of natural neurons ...
Preparation and self-aggregation properties of a series of pyrene-imidazolylidene complexes of gold (I)
(Elsevier, 2020-06-21)
This article describes the preparation of three different Au(I) complexes bearing a pyrene-imidazolylidene ligand, two of which are bound to phenyl-acetylene ligands. The supramolecular and photophysical properties of all ...
Nanoscale Perovskite‐Sensitized Solar Cell Revisited: Dye‐Cell or Perovskite‐Cell?
(Wiley‐VCH Verlag, 2020-03-20)
A general and straightforward way of preparing few nanometer-sized well-separated MAPbIxBr3-x perovskite photosensitizers on the
surface of ~1 μm thick mesoporous TiO2 photoanode was suggested via a two-step sequential ...
Unique Curve for the Radiative Photovoltage Deficit Caused by the Urbach Tail
(American Chemical Society, 2021-08-12)
The photovoltage Voc of high-performance solar cells such as GaAs
and metal halide perovskites is affected by the exponential Urbach tail in the
absorption spectrum, with an energy parameter EU. It has been observed ...

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 ...
Transition from Capacitive to Inductive Hysteresis: A Neuron-Style Model to Correlate I–V Curves to Impedances of Metal Halide Perovskites
(American Chemical Society, 2022-08-18)
Metal halide perovskite (MHP) devices often show different types of hysteresis in separate voltage domains. At low voltage, the impedance response is capacitive, and the cell gives regular hysteresis. At high voltage, the ...
