Quantification of pv power and economic losses due to soiling in Qatar
(
MDPI
, 2021 , Article)
Soiling losses of photovoltaic (PV) panels due to dust lead to a significant decrease in solar energy yield and result in economic losses; this hence poses critical challenges to the viability of PV in smart grid systems. ...

n-InAs based photo-thermo-electrochemical cells for conversion of solar to electrical energy
(
Elsevier B.V.
, 2016 , Article)
This paper presents the photo-thermo-electrochemical (PEC) response of various combinations of the n-type indium arsenide (n-InAs) photo-electrode with different counter electrodes, i.e., Ag, Al, Cu, Pb, Zn and ITO. The ...
Optimization of ITO glass/TiO2 based DSSC photo-anodes through electrophoretic deposition and sintering techniques
(
Elsevier Ltd
, 2017 , Article)
In the current study, TiO2 layers were deposited onto Indium Tin Oxide (ITO) coated glass substrates at varied voltage levels ranging from 2.5 VDC to 7.5 VDC, using Electrophoretic deposition (EPD) process. Subsequently, ...
Binary blend based dye sensitized photo sensor using PCPDTBT and MEH-PPV composite as a light sensitizer
(
Elsevier Ltd
, 2015 , Article)
In this research, we present a binary blend of two polymers, i.e., namely, poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta [2,1-b;3,4-b′]dithiophene)-alt-4,7(2,1,3-benzothiadiazole)] (PCPDTBT) and poly[2-methoxy-5-(2-ethy ...
High-Performance BiCMOS Transimpedance Amplifiers for Fiber-Optic Receivers
(
Sultan Qaboos University
, 2017 , Article)
High gain, wide bandwidth, low noise, and low-power transimpedance amplifiers based on new BiCMOS common- base topologies have been designed for fiber-optic receivers. In particular a design approach, hereafter called "A ...
Ultrahigh Aspect Ratio Copper-Nanowire-Based Hybrid Transparent Conductive Electrodes with PEDOT:PSS and Reduced Graphene Oxide Exhibiting Reduced Surface Roughness and Improved Stability
(
American Chemical Society
, 2015 , Article)
Copper nanowires (CuNWs) with ultrahigh aspect ratio are synthesized with a solution process and spray-coated onto select substrates to fabricate transparent conductive electrodes (TCEs). Different annealing methods are ...
Multiparametric Sensor Node for Environmental Monitoring Based on Energy Harvesting
(
MDPI
, 2022 , Article)
The heterogeneity and levels of chemicals released into the environment have dramatically grown in the last few years. Therefore, new low-cost tools are increasingly required to monitor pollution and follow its trends over ...
Consequence of aging at Au/HTM/perovskite interface in triple cation 3D and 2D/3D hybrid perovskite solar cells
(
Nature Research
, 2021 , Article)
Perovskite solar cells (PSCs) expressed great potentials for offering a feasible alternative to conventional photovoltaic technologies. 2D/3D hybrid PSCs, where a 2D capping layer is used over the 3D film to avoid the ...
Assessing mobile ions contributions to admittance spectra and current-voltage characteristics of 3D and 2D/3D perovskite solar cells
(
Elsevier B.V.
, 2020 , Article)
Recently, the 2D perovskite layer is employed as a capping/passivating layer in the perovskite solar cells (PSCs). The 2D perovskite layer is prepared by inserting a large-sized hydrophobic cation spacer into the perovskite ...
