Spray-on Solar Cells
Could Revolutionize EVERYTHING!
By Jeanette Joy Fisher
In a breakthrough that could reshape the energy needs of
the world as we know it, scientists have invented a
plastic solar cell that's able to turn the sun's power
into electrical energy, even on cloudy days, by harnessing
the sun's infrared rays. It's an exciting breakthrough,
leading energy theorists to predict even greater
breakthroughs as the revolutionary material is refined to
become more efficient.
The composite material can be sprayed on like paint, and
then used to generate highly portable electricity. For
instance, if a coat was covered with the material, it
could be used to power the wearer's cell phone, using both
infrared and visible light to create energy.
Theoretically, an electric vehicle coated with the
material could convert enough solar energy into
electricity to continually recharge its batteries. Coating
a rooftop with the material could easily supply a building
with its energy needs, as well. Eventually, by using
infrared, the new material is expected generate up to five
times more power than even the most efficient of today's
plastic solar cells, which typically use only about 6
percent of the sun’s available energy to create
electricity.
In the not-too-distant future, it's even possible that
large solar farms could be developed in the most sunny
areas of the world, with huge sheets of the plastic
material covering the ground. In fact, Canadian scientists
from the University of Toronto (where the material was
initially invented) have suggested that it would require
only .1 percent of the Earth's surface to be covered with
the plastic material to create enough energy to supply the
entire world's needs--without generating a single drop of
pollution--forever, since the energy would be completely
renewable.
Until this revolutionary breakthrough, plastic solar cell
technology has only made it possible to capture energy
from the sun's visible light. However, only half of the
sun's power is present in the visible spectrum--to capture
the other half, scientists needed a way to harness the
infrared spectrum.
Obtaining huge amounts of energy from the sun is no longer
a visionary concept. In fact, Japan, which is the largest
solar power market in the world, has plans to supply half
of its total residential energy needs by 2030.
It's quite possible that the Canadian solar technology
breakthrough will play a large part in helping Japan reach
that goal, and for the rest of the planet's energy needs,
as well.
