Metals in the plasmonic metamaterial absorbers for photovoltaics constitute undesired resistive heating. However, tailoring the geometric skin depth of metals can minimize resistive losses while maximizing the optical absorbance in the active semiconductors of the photovoltaic device. Considering experimental permittivity data for InxGa1-xN, absorbance in the semiconductor layers of the photovoltaic device can reach above 90%. The results here also provides guidance to compare the performance of different semiconductor materials. This skin depth engineering approach can also be applied to other optoelectronic devices, where optimizing the device performance demands minimizing resistive losses and power consumption, such as photodetectors, laser diodes, …

Based on recent advances in nanoscience, data science and the availability of massive real-world datastreams, the mesoscopic evolution of mesoscopic energy materials can now be more fully studied. The temporal evolution is vastly complex in time and length scales and is fundamentally challenging to scientific understanding of degradation mechanisms and pathways responsible for energy materials evolution over lifetime. We propose a paradigm shift towards mesoscopic evolution modeling, based on physical and statistical models, that would integrate laboratory studies and real-world massive datastreams into a stress/mechanism/response framework with predictive capabilities. These epidemiological studies encompass the variability in properties that affect performance …

Sunsense/Sunsmart Plus-Up Schools Program Final Inspection Report, Florida Solar Energy Center, Susan Schleith
FSEC Energy Research Center®
This report provides information regarding the photovoltaic systems that are associated with the 2014 Sunsense/Sunsmart School Plus-UP program. Dave Click led the project as Principal Investigator and technical expert. Susan Schleith, participated as Co-Principal Investigator and education/school liaison. Four schools participated in the program. Each of the photovoltaic systems installed at the schools was inspected by the University of Central Florida's Florida Solar Energy Center (FSEC), as well as the local authority having jurisdiction (AHJ). This report details the results of the final inspections associated with National Electric Code (NEC) and performance testing as required by the Sunsense/Sunsmart Schools Plus-UP …
