High-efficiency c-Si based interdigitated point contact back heterojunction solar cells
(
Springer New York LLC
, 2017 , Article)
We report on the modeling and performance optimization studies of point contact back heterojunction (BHJ) solar cells. BHJ solar cell technology is a combination of front heterojunction (a-Si:H/c-Si) solar cell technology ...
Recovery of rare earth elements from waste streams using membrane processes: An overview
(
Elsevier
, 2021 , Article)
Recovery of rare earth elements (REEs) has become an attractive process owing to the high costs and limited availabilities of REEs. In addition, the recovery of REEs has become a necessity because of their high toxicity ...
Influence of Surfactant Structure on the Stability of Water-in-Oil Emulsions under High-Temperature High-Salinity Conditions
(
Hindawi Limited
, 2017 , Article)
Emulsified water-in-oil (W/O) systems are extensively used in the oil industry for water control and acid stimulation. Emulsifiers are commonly utilized to emulsify a water-soluble material to form W/O emulsion. The selection ...
Instability in CH3NH3PbI3 perovskite solar cells due to elemental migration and chemical composition changes
(
Nature Publishing Group
, 2017 , Article)
Organic-inorganic halide perovskites have rapidly grown as favorable materials for photovoltaic applications, but accomplishing long-term stability is still a major research problem. This work demonstrates a new insight ...
Pilot-scale spiral wound membrane assessment for THM precursor rejection from upland waters
(
Taylor and Francis Inc.
, 2016 , Article)
The outcomes of a pilot-scale study of the rejection of trihalomethanes (THMs) precursors by commercial ultrafiltration/nanofiltration (UF/NF) spiral-wound membrane elements are presented based on a single surface water ...
Multi-layer multi-configuration time-dependent Hartree (ML-MCTDH) approach to the correlated exciton-vibrational dynamics in the FMO complex
(
American Institute of Physics Inc.
, 2016 , Article)
The coupled quantum dynamics of excitonic and vibrational degrees of freedom is investigated for high-dimensional models of the Fenna-Matthews-Olson complex. This includes a seven- and an eight-site model with 518 and 592 ...
Surface plasmon inhibited photo-luminescence activation in CdSe/ZnS core-shell quantum dots
(
Institute of Physics Publishing
, 2016 , Article)
In a composite film of Cdx Sey Zn1-x S1-y gradient core-shell quantum dots (QDs) and gold nanorods (NRs), the optical properties of the QDs are drastically affected by the plasmonic nanoparticles. We provide a careful study ...
Reaction Kinetics of Carbon Dioxide (CO2) with Diethylenetriamine and 1-Amino-2-propanol in Nonaqueous Solvents Using Stopped-Flow Technique
(
American Chemical Society
, 2016 , Article)
In this work, the reaction kinetics of carbon dioxide (CO2) with diethylenetriamine (DETA) and 1-amino-2-propanol (1-AP) in methanol and ethanol systems were measured using the stopped flow technique over a temperature ...
Hot electron and hole dynamics in thiol-capped CdSe quantum dots revealed by 2D electronic spectroscopy
(
Royal Society of Chemistry
, 2016 , Article)
Colloidal quantum dots (QDs) have attracted interest as materials for opto-electronic applications, wherein their efficient energy use requires the understanding of carrier relaxation. In QDs capped by bifunctional thiols, ...
Enhanced photovoltaic performance with co-sensitization of a ruthenium(ii) sensitizer and an organic dye in dye-sensitized solar cells
(
Royal Society of Chemistry
, 2016 , Article)
Co-sensitization is demonstrated to be an effective technique to enhance the efficiency of dye-sensitized solar cells, where an efficiency of 9.23% is achieved by mixing N3 and RK-1 dyes. The assembled solar cells are ...
