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 ...
Counterbalance between Surface and Confinement Effects As Studied for Amino-Terminated Poly(propylene glycol) Constraint in Silica Nanopores
(American Chemical Society, 2019)
Broadband dielectric spectroscopy (BDS) and orthopositronium annihilation lifetime spectroscopy (PALS) are combined to study the
molecular dynamics and the free volume of poly(propylene glycol) terminated
with amino end ...
Dynamic Control of Interference Effects Between Optical Filaments through Programmable Optical Phase Modulation
(IEEE, 2016-06)
Light beams shaped by programmable megapixel spatial light modulators (SLMs) are key to broadening the applications of photonics. In this paper, we consider the application of a SLM for the generation of two mutually ...
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 ...
Inorganic Surface Engineering to Enhance Perovskite Solar Cell Efficiency
(American Chemical Society, 2017-03-29)
The photoconversion efficiency of perovskite solar cells (PSCs) is enhanced by the deposition of inorganic nanoparticles (NPs) at the interface between the compact TiO2 electron-selective contact and the mesoporous TiO2 ...
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, ...
Diffraction-Based Phase Calibration of Spatial Light Modulators With Binary Phase Fresnel Lenses
(IEEE, 2016)
We propose a simple and robust method to determine the calibration function of phase-only spatial light modulators (SLMs). The proposed method is based on the codification of binary phase Fresnel lenses (BPFLs) onto an ...
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. ...
Electron trapping induced electrostatic adsorption of cations: a general factor leading to photoactivity decay of nanostructured TiO2
(Royal Society of Chemistry, 2017-02)
In this work, a mechanism of electron trapping induced electrostatic adsorption of electrolyte cations (ETIEA) is proposed to explain the general photoactivity decay of nanostructured TiO2 electrodes, usually occurring ...
