Diamond-based electrodes for organic photovoltaic devices
(Elsevier, 2015-03)
The present paper demonstrates the possibility of replacing indium–tin oxide (ITO) with heavily boron-doped diamond (BDD). Plasma Enhanced Chemically Vapor Deposited BDDs layers of various thicknesses were prepared containing ...
Modulating the interaction between gold and TiO2 nanowires for enhanced solar driven photoelectrocatalytic hydrogen generation
(Royal Society of Chemistry, 2015)
The interaction strength of Au nanoparticles with pristine and nitrogen doped TiO2 nanowire surfaces was
analysed using density functional theory and their significance in enhancing the solar driven photoelectrocatalyti ...
Structural and Electrical Investigation of Cobalt-Doped NiOx/Perovskite Interface for Efficient Inverted Solar Cells
(MDPI, 2020-04-30)
Inorganic hole-transporting materials (HTMs) for stable and cheap inverted
perovskite-based solar cells are highly desired. In this context, NiOx, with low synthesis temperature,
has been employed. However, the low ...
Lead Sulfide Nanocubes for Solar Energy Storage
(Wiley, 2020-04-23)
Lead sulfide (PbS) nanocubes are produced by a very simple solvothermal procedure that uses a unique molecule, ethylenediamine, as solvent and capping ligand to control the size and shape of the nanocrystals. Detailed ...
Facile kinetics of Li-ion intake causes superior rate capability in multiwalled carbon nanotube@TiO2 nanocomposite battery anodes
(Elsevier, 2014-12)
Nanotechnology produces hybrids with superior properties than its individual constituents. Here MWCNT@TiO2 composites have been synthesized by controlled hydrolysis of titanium isopropoxide over MWCNT, to be incorporated ...
Colloidal PbS and PbSeS Quantum Dot Sensitized Solar Cells Prepared by Electrophoretic Deposition
(American Chemical Society, 2012)
Here we report the developement of quantum dot sensitized solar cells (QDSCs) using colloidal PbS and PbSeS QDs and polysulfide electrolyte for high photocurrents. QDSCs have been prepared in a novel sensitizing way employing ...
Effect of organic and inorganic passivation in quantum-dot-sensitized solar cells
(American Chemical Society, 2013)
The effect of semiconductor passivation on quantum-dot-sensitized solar cells (QDSCs) has been systematically characterized for CdS and CdS/ZnS. We have found that passivation strongly depends on the passivation agent, ...
From Flat to Nanostructured Photovoltaics: Balance between Thickness of the Absorber and Charge Screening in Sensitized Solar Cells
(American Chemical Society, 2012-01)
Nanoporous metal oxide electrodes provide a high internal area for dye anchoring in dye-sensitized solar cells, but the thickness required to extinguish the solar photons also enhances recombination at the TiO2/electrolyte ...
Surface Recombination and Collection Efficiency in Perovskite Solar Cells from Impedance Analysis
(American Chemical Society, 2016-11)
The large diffusion lengths recurrently measured in perovskite single crystals and films signal small bulk nonradiative recombination flux and locate the dominant carrier recombination processes at the outer interfaces. ...
High performing PbS Quantum Dot Sensitized Solar Cells exceeding 4% efficiency: The role of metal precursor in the electron injection and charge separation
(Royal Society of Chemistry, 2013)
Here we report the preparation of high performance Quantum Dot Sensitized Solar Cells (QDSCs) based on
PbS–CdS co-sensitized nanoporous TiO2 electrodes. QDs were directly grown on the TiO2 mesostructure by
the Successive ...
