Harnessing infrared photons for photoelectrochemical hydrogen generation. A PbS quantum dot based "quasi-artificial leaf"
(American Chemical Society, 2013)
Hydrogen generation by using quantum dot (QD) based heterostructures has emerged as a promising strategy to develop artificial photosynthesis devices. In the present study, we sensitize mesoporous TiO2 electrodes with ...
Selective contacts drive charge extraction in quantum dot solids via asymmetry in carrier transfer kinetics
(Nature Publishing Group, 2013)
Colloidal quantum dot solar cells achieve spectrally selective optical absorption in a thin layer of solution-processed, size-effect tuned, nanoparticles. The best devices built to date have relied heavily on drift-based ...
Mechanism of carrier accumulation in perovskite thin-absorber solar cells
(Nature Publishing Group, 2013)
Photovoltaic conversion requires two successive steps: accumulation of a photogenerated charge and charge separation. Determination of how and where charge accumulation is attained and how this accumulation can be identified ...
Hydrophobic Pulmonary Surfactant Proteins SP-B and SP-C Induce Pore Formation in Planar Lipid Membranes: Evidence for Proteolipid Pores
(Biophysical Society, 2013-01-08)
Pulmonary surfactant is a complex mixture of lipids and specific surfactant proteins, including the hydrophobic proteins SP-B and SP-C, in charge of stabilizing the respiratory surface of mammalian lungs. The combined ...
Interpretation of Diffusion and Recombination in Nanostructured and Energy-Disordered Materials by Stochastic Quasiequilibrium Simulation
(American Chemical Society, 2013)
The main electronic feature of many nanocrystalline semiconductors and I organic materials is the presence of a distribution of localized states in the system with a broad energy dispersion. Carrier transport and recombination ...
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) ...
Determination of charge carrier mobility of hole transporting polytriarylamine-based diodes
(Elsevier, 2010)
Hole transport properties of three different side chain poly(triarylamines) have been determined by means of the analysis of steady-state current-voltage characteristics using co-planar diode structures. The interpretation ...
Theory of the impedance of charge transfer via surface states in dye-sensitized solar cells
(Elsevier, 2010)
The dynamics of trapping coupled with charge transfer is analysed in the frequency domain for a model of the dye-sensitized solar cell. We solve the steady state occupations of the surface state and the resulting recombination ...
Stochastic pumping of ions based on colored noise in bacterial channels under acidic stress
(Royal Society of Chemistry, 2016-06)
Fluctuation-driven ion transport can be obtained in bacterial channels with the aid of different types of colored noise including the biologically relevant Lorentzian one. Using the electrochemical rectification of the ...
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 ...
