In these initial experiments, the researchers studied the material in bulk form, rather than as flat sheets; Dincă says that makes the current results - including excellent electrical conductivity - even more impressive, since these properties should be better yet in a 2-D version of the material. “There’s every reason to believe that the properties of the particles are worse than those of a sheet,” he says, “but they’re still impressive.”


What’s more, this is just the first of what could be a diverse family of similar materials built from different metals or organic compounds.


“Now we have an entire arsenal of organic synthesis and inorganic synthesis,” Dincă says, that could be harnessed to “tune the properties, with atom-like precision and virtually infinite tuneability.”


Such materials, Dincă says, might ultimately lend themselves to solar cells whose ability to capture different wavelengths of light could be matched to the solar spectrum, or to improved supercapacitors, which can store electrical energy until it’s needed.


In addition, the new material could lend itself to use in basic research on the properties of matter, or to the creation of exotic materials such as magnetic topological insulators, or materials that exhibit quantum Hall effects.


“They’re in the same class of materials that have been predicted to have exotic new electronic states,” Dincă says. “These would be the first examples of these effects in materials made out of organic molecules. People are excited about that.”


that “the quality of this work, from the synthetic design strategy to the probing of the structural details and to the discovery of exceptional electrical conductivity, is outstanding.” She adds that this finding “represents a major advance in the synthetic design of novel semiconducting materials.”

Ascent Solar delivers over $750,000 single EnerPlex shipment


The CIGS based modules are designed for the consumer market


Ascent Solar Technologies says it has shipped over $750,000 of its EnerPlex series of consumer products to Fry’s Electronics for its upcoming anniversary sale.


The shipment is made up of multiple EnerPlex flagship and accessory product lines, all of which will be available for sale in Fry’s stores beginning May 12th.


The completion of this single large order surpasses not only the company’s entire Q4 2013 revenue by 30 percent, but also exceeds its EnerPlex Q1 2014 product revenue.


Richard Hashim, GM of Ascent Solar’s EnerPlex Division, says, “EnerPlex is extremely pleased to be able to provide support for the demand we have seen for our EnerPlex products through our largest retailer, Fry’s Electronics. This order is yet another example of the continuing increase in demand for EnerPlex’s ultimate portable power solution, from solar chargers to rechargeable batteries and accessories.”


“Ascent is set to achieve yet another milestone this quarter in terms of product revenue,” continues Victor Lee, President & CEO of Ascent Solar. “We are extremely pleased with the momentum and acceleration of our EnerPlex brand building and product acceptance; factors which hopefully will be the catalyst of Ascent’s rapid growth moving forward.”


Fry’s Electronics, founded in 1985 in Silicon Valley, is one an electronics retailer and says it is the go-to place for savvy and trend-setting technology consumers.

Pingyun Feng, at the chemistry department at the University of California at Riverside who was not involved in this work, says the approach used by this team is “novel and surprising,” and

With thirty-four retail locations in nine states, Fry’s provides an avenue for EnerPlex to connect with a knowledgeable, affluent and influential end-user customer base.
