pack that gives users the capability to store solar power generated from their EnerPlex Kickr IV solar chargers or from a conventional plug in power source. The charged Jumpr can then be used to recharge or power electronic devices in virtually any setting.
The Jumpr product line includes the Model 4400, rated for 4400 milliamp-hours, that can provide about 3 recharges to your smartphone. It also includes the larger Model 7800, rated for 7800 milliamp-hours, which will charge larger devices such as tablet computers.
“The EnerPlex Jumpr, with its power storage capability and compact design, is a great addition to our recently announced Kickr IV portable solar charging units. With these two innovative products everyone from backpackers to road warriors can virtually live life untethered and power their smartphones or other electronic devices off-grid,” says Victor Lee, Ascent’s President & CEO.
The EnerPlex Jumpr is available for sale standalone or bundled with Kickr IV through Ascent’s official website at
www.enerplex.biz.
In line with its previous Kickr IV announcement, Ascent will continue to pledge 10 percent of the revenues from Jumpr through the end of the year to support the American Red Cross in the continued recovery effort of Hurricane Sandy.
The EnerPlex brand represents Ascent Solar’s line of consumer products. These products, many of which are integrated with Ascent Solar’s CIGS technology, provide consumers with the ability to integrate solar into their everyday lives, while enabling them to free themselves and their electronics from the outlet.
Global Photonic Energy unveils potential grid parity GaAs solar cell
The cell which reuses gallium arsenide is 20 percent efficient and is ultra-lightweight and flexible and has a potential of $0.45 per watt
Global Photonic Energy Corporation (“GPEC”), a
developer of a sustainable Organic Photovoltaic technology, has demonstrated a thin-film solar cell that could provide electricity at grid parity, or the cost of traditionally provided electricity.
Stephen R. Forrest of the University of Michigan says the breakthrough, presented at the Fall Meeting of the Materials Research Society, is the result of substantially reduced production costs.
It is based on a patent-pending invention that reuses the same GaAs wafer multiple times to produce solar cells. This unlimited wafer reuse approach to conventional “epitaxial lift off” technology typically leads to wafer damage. Hence a very limited number (1 to 2) of wafer reuses, has the potential to reduce the cost of a typical GaAs solar cell to below $1 per Watt (peak).
“This exciting development implies that ultra-high efficiency solar cells based on gallium arsenide can eventually produce electricity at or below grid parity.” Forrest states. “Using integrated solar concentrators and our adhesive-free, cold-weld bonding technology to plastic substrates, we estimate electricity could be produced as low as $0.45 cents per Watt, compared to traditional grid parity of $1 per Watt.”
“This is a historic development for GPEC,” states Dean Ledger, President and CEO of GPEC. “In addition to its dramatically reduced cost structure, this demonstration in the University of Michigan laboratories can be used for numerous applications because these high-efficiency solar cells, deployed on roll-up plastic sheets, are ultra-lightweight and flexible. These applications include use in off-grid locations, spot powering of vehicles, mobile military equipment and satellites.” Ledger says GPEC will commercialise its technology through licensing of its intellectual property, becoming part of its foundational portfolio of more than 425 patents.
