Solar Power Without Solar Cells
A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers
could lead to solar power without traditional semiconductor-based solar cells.
The researchers found a way to make an"optical________(51)",said Stephen Rand,a professor in
the departments of Electrical Engineering and Computer Science,Physics and Applied Physics.
Light has electric and magnetic_______(52).Until now,scientists thought the effects of the mag-
netic field were so weak that they could be________(53).What Rand and his colleagues found is that at
the right intensity,when light is traveling through a material that does not_________(54)electricity,the
light field can generate magnetic effects that are 100 million times stronger than previously expected.Under
these circumstances,the magnetic effects develop strength_________(55)to a strong electric effect.
"This could lead to a new kind of solar cell without semiconductors and without absorption to produce
charge separation,"Rand said."In solar cells,the_________(56)goes into a matenal,gets absorbed and
creates heat.Here,we expect to have a very low heat load.Instead of the light being absorbed,energy is
stored in the magnetic moment.Intense magnetization can be induced by intense light and then it is ultimately
capable of providing a capacitive power________(57)."What makes this possible is a previously unde-
tected brand of"optical rectification",says William Fisher,a doctoral student in applied physics.In tradi-
tional optical rectification,light's electric field causes a charge separation,or a pulling_________(58)of
the positive and negative charges in a material.This sets up a voltage,similar to______(59)in a
battery.
Rand and Fisher found that under the right circumstances and in right types of materials,the light's
magnetic field can also create optical rectification.The light must be shone through a________(60)that
does not conduct electricity,such as glass.And it must be focused to an intensity of 10 million watts per
square centimeter. Sunlight isn't this_______(61)on its own,but new materials are being sought that
would work at lower intensities,Fisher said.
"In our most recent paper,we show that incoherent light like sunlight is theoretically almost
_________(62)effective in producing charge separation as laser light is,"Fisher said.
This new_________(63)could make solar power cheaper,the researchers say.They predict that with
improved materials they could achieve 10 percent efficiency in converting solar power to usable energy.That's
equivalent to today's commercial-grade solar cells.
"To manufacture modern solar cells,you have to do. _______(64)semiconductor processing,"
Fisher said."All we would need are lenses to focus the light and a fiber to guide it.Glassworks for
_________ (65).It's already made in bulk,and it doesn't require as much processing.Transparent
ceramics might be even better."
_________(53)
A.concerned
B.ignored
C.expected
D.noticed

[填空题]

Human beings have little direct control over the volume of
water in the atmosphere. But we produce other greenhouse gases that intensify
the effect. The IPCC estimates that rising CO2 emissions, mostly from
burning fossil fuels, account for about 60 percent of the warming observed since
1850, Carbon dioxide concentration has been increasing by about 0.3 percent a
year, and it is now about 30 percent higher than it was before the industrial
revolution.
2. The relentless accumulation of greenhouse gases
has led the IPCC to project that in the next hundred years average global
temperatures will rise by 1 to 3.5 degrees C. That may not
seem like much.
Yet the "little ice age," an anomalous cold snap that peaked from 1570 to 1730
and forced European farmers to abandon their fields, was caused by a change of
only half a degree.
