Back contacts materials used in thin film CdTe solar cells—A review

open access: yesEnergy Science & Engineering, 2021
CdTe is the leading commercial thin film photovoltaic technology with current record laboratory efficiency (22.1%). However, there is much potential for progress toward the Shockley‐Queisser limit (32%).

Study on the VCRplus Back-Up Roll Contour of 1500 mm CVC Mill

open access: yesMetals, 2023
The back-up rolls of hot strip mills wear considerably under the conditions of high temperature and heavy load, which affects the roll service period and the stability of strip profile control.

Magneto-quantum oscillations of the conductance of a tunnel point-contact in the presence of a single defect [PDF]

open access: yes, 2007
The influence of a quantizing magnetic field $H$ to the conductance of a tunnel point contact in the presence of the single defect has been considered. We demonstrate that the conductance exhibits specific magneto-quantum oscillations, the amplitude and ...

Electrodeposition of Bi2Te3 thin films onto FTO substrates from DMSO solution

open access: yesInternational Journal of Electrochemical Science, 2015
We report the pulsed electrodeposition (PED) of Bi2Te3 thin films from TeCl4 and Bi(NO3)3 precursors dissolved in dimethylsulfoxide (DMSO) onto SnO2:F coated glasses (FTO) and CdTe/FTO substrates.

Optimization of Mo/Cr bilayer back contacts for thin-film solar cells

open access: yesBeilstein Journal of Nanotechnology, 2018
Molybdenum (Mo) is the most commonly used material as back contact in thin-film solar cells. Adhesion of Mo film to soda–lime glass (SLG) substrate is crucial to the performance of solar cells. In this study, an optimized bilayer structure made of a thin

Contact Dependence of Carrier Injection in Carbon Nanotubes: An Ab Initio Study [PDF]

open access: yes, 2006
We combine ab initio density functional theory with transport calculations to provide a microscopic basis for distinguishing between good and poor metal contacts to nanotubes. Comparing Ti and Pd as examples of different contact metals, we trace back the

Invariants and Infinitesimal Transformations for Contact Sub-Lorentzian Structures on 3-Dimensional Manifolds [PDF]

open access: yes, 2014
In this article we develop some elementary aspects of a theory of symmetry in sub-Lorentzian geometry. First of all we construct invariants characterizing isometric classes of sub-Lorentzian contact 3 manifolds.

A kinetic comparison of back-loading and head-loading in Xhosa women [PDF]

open access: yes, 2011
The purpose of this study was to compare the kinetic responses associated with ground reaction force measurements to both head-loading and back-loading in a group of Xhosa women. Altogether, 16 women were divided into two groups based on their experience
