Quantum Dots that Assemble Themselves Could Bolster Quantum Photonics and Solar Cell Efficiency

Posted by Guest Editor, NREL newswire on Tuesday, March 19, 2013, In : News

Scientists from the U.S. Department of Energy's National Renewable Energy Laboratory and other labs have demonstrated a process whereby quantum dots can self-assemble at optimal locations in nanowires, a breakthrough that could improve solar cells, quantum computing, and lighting devices.

A paper on the new technology, "Self-assembled Quantum Dots in a Nanowire System for Quantum Photonics," appears in the current issue of the scientific journal Nature Materials.

Quantum dots are tiny cry...

Report Advises Utilities on Unintentional Islanding Risk for Distributed Generation

Posted by Guest Editor on Tuesday, March 12, 2013, In : News

A Sandia National Laboratories report details a procedure to quickly determine whether utilities need an additional unintentional islanding study when evaluating the proposed interconnection of new distributed generation (DG), which includes photovoltaic (PV) systems.

Islanding occurs when the DG continues to energize a load well after it is disconnected from the utility source, and when established accidentally, islanding can adversely affect personnel safety and equipment integrity. Followi...

Schools Raise the Roof on Solar Energy

Posted by Guest Editor news from NREL on Wednesday, October 17, 2012, In : Guest Blogger

In one 50-minute period last month, the Intro to Engineering students at Chatfield High School in Jefferson County, Colorado, charted the strength of solar panels at their desks, then climbed through a trap door to examine the 100-kilowatt solar array on their school's flat roof.

"You see a couple of panels that have been shattered by last year's wind storm," teacher Joel Bertelsen told the 32 students, who were peering intently at the panels when not testing the springiness of the roof. "I...

US Gov. Imposed Tariffs of Around 30% on Solar Panels from China

Posted by Guest Editor on Friday, May 18, 2012, In : News

The US government has imposed tariffs of around 30 percent on solar panels imported from China, sparking charges of “trade protectionism” from Chinese government officials and increasing friction between the two countries.

The US Commerce Department ruled yesterday in favor of American companies that charged Chinese exporters had illegally “dumped” their solar panels on the US market below fair market price.

Commerce officials will continue their investigations in the trade cases, a...
