Machine learning based photovoltaics (PV) power prediction using different environmental parameters of Qatar
(
MDPI AG
, 2019 , Article)
Photovoltaics (PV) output power is highly sensitive to many environmental parameters and the power produced by the PV systems is significantly affected by the harsh environments. The annual PV power density of around 2000 ...
Flexible thermo-electrochemical cells using Iodolyte HI-30 for conversion of low-grade heat to electrical energy
(
Royal Society of Chemistry
, 2016 , Article)
In this research work, we investigated the flexible thermo-electro chemical cells (TECs) for the conversion of low-grade heat into electrical energy in the temperature range of 20–70 °C. The TECs were fabricated using 30 ...
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 ...
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 ...
Diversity-multiplexing tradeoff for log-normal fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Although there has been a growing interest on the study of diversity-multiplexing tradeoff (DMT), the existing works are mostly restricted to the outcomes reported for Rayleigh, Rician, and Nakagami fading channels. In ...
Feasibility and performance evaluation of a 6LoWPAN-enabled platform for ubiquitous healthcare monitoring
(
John Wiley and Sons Ltd
, 2016 , Article)
Technology has revolutionized medical practices by enabling more convenient and non-intrusive monitoring of patient's health, leading to next generation ubiquitous healthcare (u-healthcare). The exploitation of the Internet ...
On the effects of combined atmospheric fading and misalignment on the hybrid FSO/RF transmission
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Free-space optical (FSO) communication is known for its various impairments such as atmospheric turbulence and misalignment fading. In this paper, we study the performance of an FSO link operating under combined path loss ...
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 ...
Structural, morphological and optical properties of PEDOT:PSS/QDs nano-composite films prepared by spin-casting
(
Elsevier B.V.
, 2016 , Article)
This paper describes the structural, morphological and optical properties of the nano-composite of poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and quantum dots (QDs). The ZnSe and CdSe QDs have been ...
Dielectric properties of Mn doped Bismuth Barium Titanate based ceramic thin films prepared by PLD technique
(
Elsevier Ltd
, 2017 , Article)
In this article, the effect of Mn doping on the permittivity and dielectric loss in 0.67BiFeO3-0.33BaTiO3 (BF-BT) based film bulk acoustic resonator test structures has been investigated. BF-BT thin films were deposited ...
