New Record For Solar Cell Power Efficiency

mdsolar writes "Renewable Energy Access is reporting that a consortium led
by researchers at the University of Delaware has achieved 42.8% efficiency
with a silicon solar cell. The method uses lower concentration (factor of 20
magnification) than the previous record holder (40.7% efficiency) so that it
may have a broader range of applications, since tolerances for pointing the
device will be larger. They are now partnering with DuPont to build
engineering and manufacturing prototypes. They expect to be in production in
2010. On a roof, such cells would require less than half the surface area to
produce the same amount of power as today's standard solar panels, which
have an efficiency of about 17%."
