Sandia, DOE Energy Storage Program, GeneSiC Semiconductor, U.S. Army ARDEC: Ultra-High-Voltage Silicon Carbide Thyristors

Increasing consumer power demand creates numerous challenges for ensuring reliable, stable power for all customers. Many energy generation technologies, particularly renewables, generate direct-current power that must be converted to alternating current before use. Power switches, known as thyristors, perform this conversion and are crucial to a reliable electricity grid. Current switches have been inefficient and [...]

George Wang’s Invited Talk at 2013 tSSL

George Wang, a senior investigator in solid-state lighting science, was invited to speak at the 7th Taiwan Solid-State Lighting (2013 tSSL). The conference was held on March 26th-27th in Taipei, Taiwan. The purpose of tSSL is “to bring together scientists and engineers actively engaged in research, development, and manufacturing on all aspects of Solid State [...]

Sandia, Endicott Interconnect Technologies, EMCORE, International Micro Industries, NREL, Universal Instruments: Solar Glitter

Sandia scientists have developed glitter-sized photovoltaic (PV) cells that have the potential to achieve the cost breakthrough necessary to move solar energy into widespread, portable use. Miniaturized solar cells are produced using Sandia’s microsystems-enabled photovoltaics (MEPV) technology, which employs microdesign and microfabrication techniques common to the semiconductor, liquid-crystal display, and microsystems industries. The PV cells [...]

EC, DHS’s S&T Directorate, Federal Emergency Management Agency: SUMMIT

Natural disasters create emergency situations that must be dealt with quickly and effectively in order to minimize injury and loss of life. Simulating such events before they occur can help emergency responders fine-tune their preparations. To create the most accurate modeling scenarios, exercise planners need to know critical event details, such as infrastructure damage and [...]

Sandia Labs, Front Edge Technology, Inc., Pacific Northwest National Lab, Univ. of California–Los Angeles: Micro Power Source

What if the batteries had the ability to recharge themselves? Just as on rooftops, a PV surface could convert the sunlight to electricity to charge the storage device. Sandia, working with Pacific Northwest National Laboratory (PNNL) and University of California at Los Angeles (UCLA), has developed the Micro Power Source, a system that integrates a [...]
