All solution processed low turn-on voltage near infrared LEDs based on core–shell PbS–CdS quantum dots with inverted device structure
(Royal Society of Chemistry, 2014)
Colloidal semiconductor quantum dots (QDs) are extraordinarily appealing for the development of light emitting devices (LEDs) due to tunable and pure color emission, brightness and solution processability. This last advantage ...
Energy Diagram of Semiconductor/Electrolyte Junctions
(American Chemical Society, 2013-12)
In electrochemistry and photoelectrochemistry, it is most common to refer the voltage to a reference electrode (RE) or in a two-electrode cell with respect to a counterelectrode (CE).(1, 2) However, in a semiconductor film ...
Photoinduced Giant Dielectric Constant in Lead Halide Perovskite Solar Cells
(American Chemical Society, 2014-06)
Organic-inorganic lead trihalide perovskites have emerged as an outstanding photovoltaic material that demonstrated a high 17.9% conversion efficiency of sunlight to electricity in a short time. We have found a giant ...
Hole conductivity and acceptor density of p-type CuGaO2 nanoparticles determined by impedance spectroscopy: The effect of Mg doping
(Elsevier, 2013)
Delafossite materials like CuGaO2 have appeared as promising p-type semiconductor materials for their exploitation in tandem dye sensitized solar cells and water splitting photoelectrochemical cells. However, the intrinsic ...
Membrane Potential Bistability in Nonexcitable Cells as Described by Inward and Outward Voltage-Gated Ion Channels
(American Chemical Society, 2014-10)
The membrane potential of nonexcitable cells, defined as the electrical potential difference between the cell cytoplasm and the extracellular environment when the current is zero, is controlled by the individual electrical ...
Photocurrent enhancement in dye-sensitized photovoltaic devices with titania–graphene composite electrodes

Photovoltaic performance of dye-sensitized solar cell (DSC) devices based on a new titania–graphene paste has been investigated using Impedance Spectroscopy (IS) technique. The results provide key information about device ...
Effect of Mesostructured Layer upon Crystalline Properties and Device Performance on Perovskite Solar Cells
(American Chemical Society, 2015-04)
One of the most fascinating characteristics of perovskite solar cells (PSCs) is the retrieved obtainment of outstanding photovoltaic (PV) performances withstanding important device configuration variations. Here we have ...
Entropy–enthalpy compensation at the single protein level: pH sensing in the bacterial channel OmpF
(The Royal Society of Chemistry, 2014)
The pH sensing mechanism of the OmpF channel operates via ligand modification: increasing acidity induces the replacement of cations with protons in critical binding sites decreasing the channel conductance. Aside from the ...
Substitution of a hydroxamic acid anchor into the MK-2 dye for enhanced photovoltaic performance and water stability in a DSSC

An efficient synthetic protocol to functionalize the cyanoacrylic acid anchoring group of commercially
available MK-2 dye with a highly water-stable hydroxamate anchoring group is described. Extensive
characterization ...
Enhancement of Efficiency in Quantum Dot Sensitized Solar Cells Based on CdS/CdSe/CdSeTe Heterostructure by Improving the Light Absorption in the VIS-NIR Region
(Elsevier, 2017-09-01)
In this work, we demonstrate an enhancement of photocurrent in QDSSCs based on CdS (QDs)/CdSe Quantum rods (QRs)/CdSeTe (QDs) heterostructure due to the increased photon harvesting in the VIS-NIR region. The photo-conversion ...
