Triumphing over Charge Transfer Limitations of PEDOT Nanofiber Reduction Catalyst by 1,2-Ethanedithiol Doping for Quantum Dot Solar Cells
(American Chemical Society, 2017)
Charge transfer between a conducting polymer-based counter electrode (CE) and a polysulfide (S2–/Sn2–) electrolyte mediator is a key limitation to improvements of solar energy conversion efficiency (ECE) in quantum-dot-sensitized ...
Tunable hysteresis effect for perovskite solar cells
(Royal Society of Chemistry, 2017-09-14)
Perovskite solar cells (PSCs) usually suffer from a hysteresis effect in current–voltage measurements,
which leads to an inaccurate estimation of the device e
fficiency. Although ion migration, charge trapping/
detrapping, ...
Fluctuation-Driven Transport in Biological Nanopores. A 3D Poisson–Nernst–Planck Study
(MDPI, 2017)
Living systems display a variety of situations in which non-equilibrium fluctuations
couple to certain protein functions yielding astonishing results. Here we study the bacterial channel
OmpF under conditions similar to ...
Selective Growth of Layered Perovskites for Stable and Efficient Photovoltaics
(Royal Society of Chemistry, 2018-11)
Perovskite solar cells (PSCs) are promising alternatives toward clean energy because of their high-power
conversion efficiency (PCE) and low materials and processing cost. However, their poor stability under
operation ...
Molecular Characterization of the Viroporin Function of Foot-and-Mouth Disease Virus Nonstructural Protein 2B
(American Society for Microbiology, 2018-12)
Nonstructural protein 2B of foot-and-mouth disease (FMD) virus (FMDV) is comprised of a small, hydrophobic, 154-amino-acid protein. Structure-function analyses demonstrated that FMDV 2B is an ion channel-forming protein. ...
Fabrication of gold nanoparticles in Therminol VP-1 by laser ablation and fragmentation with fs pulses
(IOP Science, 2014-10-22)
This letter reports on a physical method to produce highly pure, size-controlled and well-dispersed spherical gold nanoparticles (NPs) in Therminol VP-1 by pulsed laser ablation in liquids (PLAL) using a 30 fs Ti:Sapphire ...
On Mott-Schottky analysis interpretation of capacitance measurements in organometal perovskite solar cells
(AIP Publishing, 2016)
Capacitance response of perovskite-based solar cells (PSCs) can be exploited to infer underlying physical mechanisms, both in the materials bulk and at outer interfaces. Particularly interesting is applying the depletion ...
Molecular relaxation and ionic conductivity of ionic liquids confined in apoly(vinylidenefluoride) polymer matrix: Influence of anion and cation type
(Elsevier, 2019)
Blends of poly(vinylidenefluoride) (PVDF) and ionic liquids (ILs) with different cations and anions have beenprepared by solvent casting. The IL content was the same in all blends of the series. Molecular relaxation andionic ...
Tunable Open Circuit Voltage by Engineering Inorganic Cesium Lead Bromide/Iodide Perovskite Solar Cells
(Nature Publishing Group, 2018)
Perovskite solar cells based on series of inorganic cesium lead bromide and iodide mixture, CsPbBr3-xI x , where x varies between 0, 0.1, 0.2, and 0.3 molar ratio were synthesized by two step-sequential deposition at ambient ...
Channel-Inactivating Mutations and Their Revertant Mutants in the Envelope Protein of Infectious Bronchitis Virus
(American Society for Microbiology, 2016-12)
It has been shown previously in the severe acute respiratory syndrome coronavirus (SARS-CoV) that two point mutations, N15A and V25F, in the transmembrane domain (TMD) of the envelope (E) protein abolished channel activity ...
