Clear visualization and understanding of luminescence properties of grain interiors and grain boundaries in polycrystalline thin-film photovoltaic materials are crucial to achieving high-performance solar cells. Luminescence-based measurements, for example

Non-nulling Protocols for Fast, Accurate, 3-D Velocity Measurements in Stacks

July 28, 2023
Author(s)
Iosif Isaakovich Shinder, Aaron Johnson, James Filla, Vladimir B. Khromchenko, Michael R. Moldover, Joey Boyd, John D. Wright, John R. Stoup
We present protocols for making fast, accurate, 3-D velocity measurements in the stacks of coal-fired power plants. The measurements are traceable to internationally-recognized standards; therefore, they provide a rigorous basis for measuring and/or

Artificial Intelligence-Assisted Edge Computing for Wide Area Monitoring

July 7, 2023
Author(s)
Bin Hu, Hamid Gharavi
The massive digital information generated in conjunction with the ever-increasing phasor measurement data in the power grid has led to a tremendous constraint on the analysis and timely processing of real-time data. Under these conditions, leveraging

What limits the voltage of GaAs photovoltaic devices under low indoor light?

June 19, 2023
Author(s)
Behrang Hamadani, Margaret Stevens, Matthew Lumb, Kenneth Schmieder
The external radiative efficiency of a photovoltaic device is a useful metric to compare different photovoltaic technologies and material systems. However, under low-intensity indoor lighting, a particular open-circuit voltage dependence arises that cannot

Assessment of a Parachor Model for the Surface Tension of Binary Mixtures
