BOSTON - A company trying to harness energy from sunlight and interior
light to wirelessly power everything from cell phones to signboards now
has financial backing from the White House.
President Bush's
program to help solar energy compete with conventional electricity
sources will help fund Konarka Technologies' development of flexible
plastic solar cell strips — material that could be embedded into the
casings of laptop computers and even woven into power-producing
clothing to energize digital media players or other electronics.
The technology, which received its first Pentagon funding three years ago, offers a lightweight, flexible alternative to conventional rigid photovoltaic cells on glass panels.
Energy Secretary Samuel Bodman
is scheduled Thursday afternoon to tour Konarka's headquarters in a
former textile mill in Lowell, where he's expected to announce funding
from Bush's Solar America Initiative.
The award amount and other details were to be announced in a news
conference at Konarka, a six-year-old private company that has
attracted nearly $60 million in venture capital funding.
Konarka's nearly $10 million in grant money to date from U.S. and
European governments includes funding from the Pentagon to supply
lightweight portable battery chargers and material for tents to draw
power from sunlight.
Chief Executive Howard Berke said the new White House support is a milestone for Konarka.
The first commercial product using Konarka's technology isn't
expected to hit the market until next year, and the company isn't
saying what that product might be. Konarka expects to provide
prototypes in the second half of this year to commercial partners that
would bring the technology to market.
Konarka's approach "is potentially a great breakthrough technology,
but like all breakthroughs, they don't happen instantaneously," Berke
said in a phone interview.
Observers say Konarka has a good chance of becoming a leader in
solar power, an industry enjoying a recent surge in initial public
stock offerings by startup companies as well as growing investments
from traditional energy companies — for example, one of Konarka's
financial backers is Chevron Corp.
Konarka's development of plastic solar cell strips that can be
manufactured like rolls of photographic film "has the promise of
becoming a low-cost manufacturing technique," said Jeffrey Bencik, a
Jefferies & Co. analyst who follows the solar industry. "Some of
their laboratory production has worked as advertised. But can they
mass-produce it and get the same result? That's the biggest question."
Among developers of solar technology for small-scale uses, Konarka
is "definitely doing the best job at developing what ultimately will
have to be a mass-manufactured material," said Dan Nocera, a
Massachusetts Institute of Technology chemistry professor.
However, Nocera said it remains to be seen whether Konarka's
so-called "Power Plastic" is sufficiently chemically stable to convert
energy efficiently both when light is dim and when it's bright.
Konarka, which takes its name from an ancient temple in India
dedicated to the sun god Surya, was founded by Berke and Alan Heeger,
who shared the 2000 Nobel Chemistry prize for showing that certain
plastics can be made to conduct electricity.
The discovery about polymers — long considered to be useful only as
electrical insulators — led to the development of new types of plastics
to create flexible and lightweight alternatives to traditional solar
cells on heavy glass panels.
Konarka developed low-cost plastics that could be used as the top
and bottom surfaces of the photovoltaic cell. The 50-employee company
says it has more than 280 patents and patent applications for
materials, manufacturing and other processes and devices.
The company says its solar cells are efficient across a much broader
spectrum of light than traditional cells, allowing them to draw energy
from both the sun and indoor lighting.
Konarka says its material is lightweight and flexible so that it can
be colored, patterned and cut to fit almost any device. The firm
envisions embedding its material in cell phones, laptops and toys to
provide power on the go. Clothing could be woven with the material to
supply power for handheld electronics, and signboards, traffic lights
and rooftops could be fitted with solar strips.
Berke foresees wide use of such technology in the developing world and areas off the electrical grid.
To that end, Berke said Konarka has held confidential
discussions with the manufacturer of an inexpensive portable computer
developed for the nonprofit One Laptop Per Child project, which seeks
to provide computers to young students in the developing world. The
project's current design features a hand crank for charging batteries.
"In the developing world, great demand exists for off-the-grid support of electronic devices," Berke said.
