Phonon manipulation with phononic crystals.

Description: In this work, we demonstrated engineered modification of propagation of thermal phonons, i.e. at THz frequencies, using phononic crystals. This work combined theoretical work at Sandia National Laboratories, the University of New Mexico, the University of Colorado Boulder, and Carnegie Mellon University; the MESA fabrication facilities at Sandia; and the microfabrication facilities at UNM to produce world-leading control of phonon propagation in silicon at frequencies up to 3 THz. These efforts… more

Field Evaluation of the Potential for Creep in Thermoplastic Encapsulant Materials: Preprint

Description: There has been recent interest in the use of thermoplastic encapsulant materials in photovoltaic modules to replace chemically crosslinked materials, e.g., ethylene-vinyl acetate. The related motivations include the desire to: reduce lamination time or temperature; use less moisture-permeable materials; use materials with better corrosion characteristics or with improved electrical resistance. However, the use of any thermoplastic material in a high-temperature environment raises safety and per… more

Glass Ceramic Formulation Data Package

Description: A glass ceramic waste form is being developed for treatment of secondary waste streams generated by aqueous reprocessing of commercial used nuclear fuel (Crum et al. 2012b). The waste stream contains a mixture of transition metals, alkali, alkaline earths, and lanthanides, several of which exceed the solubility limits of a single phase borosilicate glass (Crum et al. 2009; Caurant et al. 2007). A multi-phase glass ceramic waste form allows incorporation of insoluble components of the waste by d… more

NREL Designs Promising New Oxides for Solar Cells (Fact Sheet)

Description: High-efficiency, thin-film solar cells require electrical contacts with high electrical conductivity, and the top contact must also have high optical transparency. This need is currently met by transparent conducting oxides (TCOs), which conduct electricity but are 90% transparent to visible light. Scientists at the National Renewable Energy Laboratory (NREL) have derived three key design principles for selecting promising materials for TCO contacts. NREL's application of these design principle… more

Properties of Bulk Sintered Silver As a Function of Porosity

Description: This report summarizes a study where various properties of bulk-sintered silver were investigated over a range of porosity. This work was conducted within the National Transportation Research Center's Power Device Packaging project that is part of the DOE Vehicle Technologies Advanced Power Electronics and Electric Motors Program. Sintered silver, as an interconnect material in power electronics, inherently has porosity in its produced structure because of the way it is made. Therefore, interes… more
