Cu(In,Ga)Se2 thin films were prepared using the classical two-step process approach. In the first step, the metallic precursors were deposited on the soda-lime glass substrates by electron-beam evaporation following the Cu/In/Ga... sequence. The selenization, called the second step, was produced in a rapid thermal processor. This process performed under nitrogen atmosphere of 200 Torr at 200°C ...

The physical data of the semiconductor materials used in the design of a CIGS absorber based thin film photovoltaic cell have been presented in this data article. Besides, the values of the contact parameter and operating conditions of the cell have been reported. Furthermore, by conducting the simulation with data corresponding to the device structure: soda-lime glass (SLG) substrate/Mo back-c...

In this study, a non-selenized CuInGaSe2 (CIGS) solar device with textured zinc oxide (ZnO) antireflection coatings was studied. The ZnO nanostructure was fabricated by a low-temperature aqueous solution deposition method. With controlling the morphology of the solution-grown tapered ZnO nanorod coatings, the average reflectance of the CIGS solar device decreased from 8.6% to 2.1%, and the ener...

This study examined the impact of four variables pertaining to the use of e-cigarettes (e-cigs) on cravings for tobacco cigarettes and for e-cigs after an overnight abstinence period. The four variables were the nicotine level, the sensorimotor component, the visual aspect, and the aroma of the e-cig. In an experimental study, 81 participants without prior vaping experience first got acquainted...

We assessed the roles of perceived satisfaction and perceived danger and vaping-product-type as correlates of more frequent use of vaping products. In a baseline assessment of a longitudinal study of US Army Reserve/National Guard Soldiers and their partners (New York State, USA, 2014-2016), participants were asked about current use of vaping products (e-cigarettes) and perceived satisfaction a...

OF DISSERTATION DEVICE PHYSICS OF Cu(In,Ga)Se2 THIN-FILM SOLAR CELLS Thin-film solar cells have the potential to be an important contributor to the global energy demand by the mid-21st-century. Cu(In,Ga)Se2 (CIGS) solar cells, which have achieved laboratory efficiencies close to 20%, are highly attractive, because their band gap is near the optimal value, their polycrystallinity is not signific...

The implementation of an oxide layer with contact openings to the Cu(In,Ga)Se2 (CIGS) interfaces has become especially popular reduce recombination losses, resulting in a higher open-circuit voltage. While implementing this approach on back surface is straightforward, it more complicated for front due roughness absorber as well material selection constraints imposed by further processing steps....

With high absorption coefficient (104 cm?1), optimal bandgap (~1.5 eV), low toxicity and the abundance of its constituent elements, kesterite (Cu2ZnSnS4 or CZTS) displays properties an ideal photovoltaic material. Kesterite is structurally analogous to chalcopyrite (Cu2InGaS2 CIGS) can thus be produced through already established techniques for synthesis commercial CIGS. Though CIGS- CdTe-based...

This study investigates the emerging harmonic stability concerns to be addressed by grid planners in generation interconnection studies, owing to the increased adoption of renewable energy resources connected to the grid via power electronic converters. The wideband and high-frequency electromagnetic transient (EMT) characteristics of these converter-interfaced generators (CIGs) and their inter...
