A comparative study on the performance of hybrid solar cells containing ZnSTe QDs in hole transporting layer and photoactive layer
(
Springer Netherlands
, 2016 , Article)
In this paper, ZnSTe quantum dots-based hybrid solar cells (HSC) with two different device architectures have been investigated. The improved performance of the poly(3-hexylthiophene) (P3HT) and [6,6]phenyl C71 butyric ...
Impact of moisture contents on the performance of organic bi-layer ITO/OD thermo-electric cells
(
Springer New York LLC
, 2016 , Article)
We propose a bi-layer thermo-electric cell based on elastic indium tin oxide (ITO) substrate and organic semiconductor orange dye (OD). It is observed that thermo-electric voltages are ~30% higher in bi-layer ITO/OD cell ...
Fabrication of flexible conductive films by rubbing in technology for application in elastic thermo-electric cells
(
Elsevier B.V.
, 2019 , Article)
This method solves the problem of fabrication of flexible elastic conductive thin film samples for thermoelectric applications. For this purpose, rubbing in technology at room temperature condition has been used which is ...
Lithium capture in seawater reverse osmosis (SWRO) brine using membrane-based capacitive deionization (MCDI) system
(
Qatar University Press
, 2021 , Poster)
Lithium-battery based industries including vehicles, electronics, fusion and thermonuclear, consume lithium rapidly, which raises the need for developing a lithium recovery system. Lithium global market consumption in 2016 ...
Optimum sintering method and temperature for cold compact Bismuth Telluride pellets for thermoelectric applications
(
Qatar University Press
, 2021 , Poster)
This work intends to investigate the optimum sintering method and temperature that can improve the efficiency of bismuth telluride cold compact pellets for thermoelectric applications. Different p-type and n-type bismuth ...
Colloidal distribution of the PCPDTBT and VOPcPhO in the organic amalgam thin films and their optical properties
(
Springer Verlag
, 2017 , Article)
In this article, we investigated the optical properties and colloidal distribution of the PCPDTBT and VOPcPhO in the organic amalgam thin films prepared by spin-coating technique. A very even dispersion of donor and acceptor ...
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 ...
Facile and Novel LiAlO2 Film Electrodes for Energy Efficient Li recovery from Seawater Reverse Osmosis (SWRO) Brine
(
Qatar University Press
, 2021 , Poster)
Concentration of Li in seawater is too low at 0.17 ppm despite its high content altogether with a reported 230 billion tons. Hence, seawater is not a practical source to recover Li from; Li is largely extracted by solar ...
2D-MXene as an additive to improve the power conversion efficiency of monolithic perovskite solar cells
(
Elsevier B.V.
, 2022 , Article)
In this study, two-dimensional (2D) material-MXene has been utilized as an additive in perovskite (MAPbI3) from 0 to 20 vol.% with an increment of 5 vol.%. The effect of different vol.% of 2D-MXene on monolithic perovskite ...
Integration of the inexpensive CuNWs based transparent counter electrode with dye sensitized photo sensors
(
Royal Society of Chemistry
, 2016 , Article)
We demonstrate, a newly developed, inexpensive transparent conducting electrode (TCE) based on copper nanowires (CuNWs) combined with reduced graphene oxide (rGO) and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate ...
