How the Charge-Neutrality Level of Interface States Controls Energy Level Alignment in Cathode Contacts of Organic Bulk-Heterojunction Solar Cells
(American Chemical Society, 2012-04)
Electronic equilibration at the metal–organic interface, leading to equalization of the Fermi levels, is a key process in organic optoelectronic devices. How the energy levels are set across the interface determines carrier ...
A Frequency Domain Analysis of the Excitability and Bifurcations of the FitzHugh–Nagumo Neuron Model
(American Chemical Society, 2021-11-18)
The dynamics of neurons consist of oscillating patterns of a membrane potential
that underpin the operation of biological intelligence. The FitzHugh−Nagumo (FHN) model
for neuron excitability generates rich dynamical ...
Series resistance in organic bulk-heterojunction solar devices: Modulating carrier transport with fullerene electron traps
(Elsevier, 2012)
Series resistance is one of the key parameters affecting the performance of organic photovoltaic devices. Several electronic mechanisms arising from different structures within the solar cell can contribute to increasing ...
Light intensity modulated impedance spectroscopy (LIMIS) in all-solid-state solar cells at open-circuit
(Elsevier, 2020)
Potentiostatic impedance spectroscopy (IS) is a well-established characterization technique for elucidating the electric resistivity and capacitive features of materials and devices. For solar cells, by applying a small ...
Solar Fuels. Photocatalytic Hydrogen Generation
(American Chemical Society, 2013)
The necessity for developing clean energy technology has led to the surge in renewable energy research. A major effort is in discovering new approaches for producing transportable fuels. Hydrogen, which possesses the highest ...
Water Oxidation at Hematite Photoelectrodes with an Iridium-Based Catalyst
(American Chemical Society, 2013)
The iridium complex [Cp*Ir(H2O)3](SO 4) was used as an organometallic source for the electrodeposition of iridium oxide onto Fe2O3. The new iridium-containing electrode allowed us to study the coupling between the ...
Tunable light emission by exciplex state formation between hybrid halide perovskite and core/shell quantum dots: Implications in advanced LEDs and photovoltaics
(American Association for the Advancement of Science, 2016)
We report the first observation of exciplex state electroluminescence due to carrier injection between the hybrid lead halide perovskite (MAPbI3–xClx) and quantum dots (core/shell PbS/CdS). Single layers of perovskite (PS) ...
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 ...
Enhanced Conductivity of Composite Membranes Based on Sulfonated Poly(Ether Ether Ketone) (SPEEK) with Zeolitic Imidazolate Frameworks (ZIFs)
(MDPI, 2018)
The zeolitic imidazolate frameworks (ZIFs) ZIF-8, ZIF-67, and a Zn/Co bimetallic mixture
(ZMix) were synthesized and used as fillers in the preparation of composite sulfonated poly(ether
ether ketone) (SPEEK) membranes. ...
Engineered Diffraction Gratings for Acoustic Cloaking
(American Physical Society, 2019)
We show that engineered diffraction gratings can considerably simplify the design of acoustic ground
cloaking devices. Acoustic reflecting gratings are designed in such a way that all the incident energy is
channeled ...
