New technology that allows for wireless charging of electronic devices
could make a rarity of cord jungles like the one in this image, captured
this year at a power generation station in New York City during the
blackout caused by Hurricane Sandy.
A mobile phone that charges in your pocket, a flat-screen TV that
needs no power cord, a car fueled by a cordless panel in the floor: In a
nondescript building just outside Boston, these and other applications
of wireless electricity signal a future with fewer snaking cables.
WiTricity,
a company spun off from research at the Massachusetts Institute of
Technology (MIT), aims to redefine how people use energy, making it
possible to power devices without ever plugging them into an outlet. In
WiTricity's lab, various devices run on power transmitted via electric
coils through the air.

Devin Coldewey , NBC News Record set in solar cell efficiency - with the light of a thousand suns
Scientists at the U.S. Department of Energy have created a solar cell
that can convert 44 percent of sunlight hitting it into electrical
energy, setting a new record for solar cell efficiency. But it was only
achieved by multiplying the power of the sun by nearly 1,000.
The ongoing research is being done at the III-V Multijunction Photovoltaics group at the Department of Energy's National Renewable Energy Laboratory, where the previous record of 43.5 percent was set. So while it's not a huge leap in efficiency, it's still a record.

The 2012 solar year in review and what lies ahead in 2013
During 2012, many PV manufacturers endured a long, uphill battle,
staggering under steep price cuts, excess inventory, shrinking margins
and political headwinds; and all the while, jostling for position with
other technologies. However, those that have demonstrated the stamina to
survive, and that can hold their ground in 2013, have a chance at
remaining in top demand for years to come.
Manipulating Light to Double Solar Power Output
An ARPA-E project will use advanced, nanostructured materials to
make solar cells that convert far more of the energy in sunlight into
electricity.
- By Kevin Bullis on December 28, 2012
In the new research effort, Harry Atwater, a professor of applied physics and materials science at Caltech, plans to use precisely structured materials to sort sunlight into eight to 10 different colors and direct those to solar cells with semiconductors that are matched perfectly to each color. As a result, more of the solar spectrum will be absorbed, and the energy contained in each slice of the spectrum will be converted mostly to electricity, rather than heat.

Wind, solar power paired with storage could be cost-effective way to power grid
Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today’s electricity expenses, according to new research ("Cost-minimized combinations of wind power, solar power and electrochemical storage, powering the grid up to 99.9% of the time") by the University of Delaware and Delaware Technical Community College. | |
A well-designed combination of wind power, solar power and storage in batteries and fuel cells would nearly always exceed electricity demands while keeping costs low, the scientists found. |

Grid Parity In Sight for New Low-Cost Solar Cell
Grid Parity In Sight For New Low-Cost Solar Cell (via Clean Technica)
That light barreling down upon us from the end of the tunnel is solar power as cheap as fossil fuels. The latest breakthrough is a low-cost solar cell manufactured with the help of Gallium Arsenide, a compound of the “poor metal” gallium and arsenic. It definitely does not sound like something…

at a Potential $0.45 per watt
MEDFORD LAKES, N.J., December 7, 2012 – Global Photonic Energy Corporation (“GPEC”), a leading
developer of a sustainable Organic Photovoltaic (OPV™) technology that enables
ultra low-cost solar power generation and exciting new product capabilities,
announces the demonstration of a thin-film solar cell that can potentially
provide electricity at grid parity, or the cost of traditionally provided
electricity.
Dr. Stephen R. Forrest of the University of Michigan said 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 Gallium Arsenide wafer multiple times to produce solar cells. This unlimited wafer reuse approach to conventional “epitaxial lift off” technology that typically leads to wafer damage, and hence only a very limited number (1 to 2) of wafer reuses, has the potential to reduce the cost of a typical Gallium Arsenide 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.” Dr. Forrest stated. “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,”
stated 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.” Mr. Ledger said GPEC will commercialize its technology through
licensing of its intellectual property, becoming part of its foundational
portfolio of more than 425 patents.
