The document discusses infrared plastic solar cells and how they can improve upon conventional solar cells. Infrared plastic solar cells use nano particles called quantum dots combined with a polymer material that can detect energy in the infrared spectrum. This allows them to generate electricity even on cloudy days when visible light cannot pass through clouds but infrared rays can. Infrared plastic solar cells are 30% more efficient than conventional plastic solar cells, are compact in size, can be shaped more flexibly, and require less material to produce compared to conventional bulky solar panels. However, their production costs remain higher currently and they have a shorter lifetime of 5-7 years when continuously exposed to sunlight.

2. ABSTRACT
The light from the Sun is a non-vanishing renewable source of energy which is free
from environ-mental pollution and noise. It is very difficult for us to survive without
electricity, with the help of electricity we are able to drive so many machines which are
helpful to us but the biggest problem is that what happens if the coal is exhausted?
Because most of the electricity is generated by burning of coal in power plants.
Although burning of fossil fuels are the main cause of air pollution but there are many
other ways to generate electricity for example: Turbines, Windmills, Solar cells etc. Our
main focus is the use of solar cell, as the sun is the ultimate source of energy but we
are able to consume only 1/10,000th part of sun’s energy. If we are able to consume
its power more efficiently then we are able to solve so many problems of our planet
without polluting the environment. Now days we are able to consume only Twenty
percent of energy at most by CdTe solar panels but with the help of infrared plastic
solar cell we can make it 30 percent more efficient, even the best plastic solar cells
efficiency is only 6 percent.

4. Conventional Solar Cell
• A solar cell is a device that convert the light energy
into electrical energy.
• Built from semiconductor
• Usually mono-crystalline or poly-crystalline materials
are needed for higher efficiency
• Convert 35% sun energy into solar energy

5. How it work solar cell

6. Working Principle

7. Application
• To drive solar powered vehicles.
• Power for facilities like repeater stations for TV, radio
etc.
• Generating electricity for space vehicles
• As an off grid energy source.
• Alternative energy source for house hold purpose
where normal electricity is not feasible.

8. INFRARED PLASTIC SOLAR CELL

9. Infrared plastic solar cell
• We all know that, we are not able to harness sun’s energy in
cloudy days but with the help of infrared plastic solar cells we are
able to do it.
• The basic origin of idea is that the visible rays of the sun are not
able to pass through clouds while the infrared rays are able to pass
through it.
• The Plastic material uses nanotechnology
• Nano particles called quantum dots are combined with polymer to
make the plastic that can detect energy in Infrared

12. HOW DO PLASTIC SOLAR CELL CHANGE LIGHT INTO
ELECTRICITY
Sunlight creates a plus (+) and a
minus (−) charge at the interface
between two polymers. The (−)
charge moves to the (−) pole of
the solar cell and the (+) charge
to the (+) pole. These poles work
just like those in a battery, but
are powered by the sun and
never run out as long as the sun
shines.

18. Advantages
• They are 30%more efficient to conventional plastic solar cell.
• Conventional solar cells are bulky panels, it is compact.
• It can be modified into any shape such that it is sewn into fabrics.
• Lesser material is required for manufacturing.
• No bigger plants are required for production.
• It is useful for those areas where there is always a cloudy climate.
• They are flexible such that they can be modified into any desired
shape.

19. Limitations
• The biggest problem is cost effectiveness, but if the
production increases then cost will decrease.
• It has a life time of 5 to 7 year, if continuously exposed to
sunlight.
• It requires constant monitoring and maintenance due to its
weak strength.

20. Application
• It will be used to power light houses in sea.
• It is painted on a hydrogen power car where it can
continuously convert into electrical energy.
• Due to its compact size it is used in mass energy
generation that it should power a whole area.
• It will be used in ships for electricity generation while
sailing.

22. Future scope
• Improve the time span of plastic solar cell for widely
use
• Decrease the cost of manufacture of plastic solar cell
• Improve efficiency of plastic solar cell.

23. Conclusion
The infrared plastic solar cells are compact in nature. No bigger
plants are required for manufacturing and they are able to
generate electricity even on cloudy day. In near future it may be
possible that some methods will be developed to increase its life
span. It is modified into any shape and size above Nano level.
There is no restriction of installation due to its light weight and
also it is easier to transport it from on placee to another place
and due to printing technology it is cheaper than the
conventional solar cell. We did not require a big budget.
