The photovoltaic industry is particularly sensitive to cost, and while pushing the envelope on conversion efficiency is a priority, efforts to reduce manufacturing costs is also a priority. Toward this end, TetraSun Inc. and the National Renewable Energy Laboratory have developed TetraCell solar cells, which offer a bifacial, high-efficiency ($3.09 per Watt-peak) solution for photovoltaic applications.

Numerous space probes have taken advantage of radioisotope thermoelectric generators (RTGs) powered by plutonium. However, the end of the Cold War has brought about a shortage of plutonium. In collaboration with NASA Glenn Research Center and National Security Technologies, Los Alamos National Laboratory has developed an alternative type of nuclear reactor, one that uses plentiful uranium as its fuel source.
Lawrence Berkeley National Laboratory’s Universal Smart Window (USW) Coating, constructed from an advance nanocrystal conducting oxide-base electrochromatic material embedded in a transition-metal-oxide matrix, is the first window coating to maximize thermal glare that enables dynamic control over heat-producing near-infrared radiation (NIR) and visible light from the sun independent of each other.
Lithium-ion battery separators prevent the anode and cathode layers from contacting each other, allowing cell potential to be maintained and safe operation of the battery. The SYMMETRIX HPX-F polymer-ceramic composite separator, developed by Porous Power Technologies and Oak Ridge National Laboratory, achieves this functionality while improving safety over conventional polyolefin membranes.
The worldwide market for portable electronic devices is quickly growing. These devices are predominantly battery-driven, and a challenge looms for maintaining, charging and disposing of these millions of batteries. Lawrence Berkeley National Laboratory’s Bacteriophage Power Generator offers a potential alternative.
Currently, electric grids have limited ability to store excess energy, so electricity must constantly be generated to perfectly match demand. Hence, power generation, transmission and distribution must accommodate the maximum demand of conditions and must include significant standby generation capacity. This adds capital expense, and forces power plants to idle or operate at non-efficient conditions. United Technologies Research Center has developed a flow-battery technology—called PureStorage—that provides affordable, safe, energy-efficient and readily deployable electrical energy storage.
Understanding and controlling temperature is necessary for the successful operation of battery packs in electric-drive vehicles (EDVs). Isothermal Battery Calorimeters (IBCs), developed by National Renewable Energy Laboratory and NETZSCH North America, are the only calorimeters that can accurately measure heat generated from batteries used in EDVs—with a baseline sensitivity of 10 mW and heat detection as low as 15 J—while being charged and/or discharged.
