Biogenic-The Powerful Solarcell
A genetically engineered bacterium that uses dye
to convert light to energy . This ultimately could
help capture solar power at places which are
mostly cloudy. Scientist in British Columbia have
built a cheap, sustainable solar cell from
E.coil,creating a solar cell. This is named
as"biogenic".It was made from living organisms.
This is not the first experimental biogenic solar
cell. What made it different was the ability to
have more powerful current, they said. Also it
works in dim light as well as in bright light.
Solar cells are the building blocks of solar panels.
Any material that can excited or energized
sufficiently by light to release electrons can be
used in solar cells to generate electricity. In
biogenic solar cells, the material "excited" by
light is biological-in this case, the dye-compared
to conventional, or inorganic, solar cells which
use crystalline silicon to generate electrons. the
anode of the solar cell, comprised of biogenic
material made of lycopene-producing bacteria
that are coated with nano particles.
Their solution is in expensive and ultimately
"could perform at comparable efficiencies as
conventional photovoltaic. Even if these cells
don't reach the same strength as conventional
cells, the researchers believe they could play an
important role in certain low-light setting such as
mines or in deep sea exploration. Biogenic solar
cells will be a useful complement to inorganic
solar cell technology Even in its infancy, the
technology has already throwing up some
promising applications. Exploring low- light
environments such as mines requires the use of
sensors that could be powered with biogenic cells
such as the one.
These innovations using natural resource
contribute a lot to the technological field as well
as reduce the carbon usage.
