3. INTRODUCTION
 The plastic solar cells uses nanotechnology and contains the
first solar cells able to harness the sun’s invisible, infrared rays.
 Plastic solar cells could one day becomes five more times more
efficient that current solar cell technology.
 Plastic solar cell can turn the suns power into electric energy
even on a cloudy day.
 The working of this type of solar cells is same as that of
conventional solar cells but these solar cells are of small size
and harness all the rays trom sun’s radiation.
 Because of their small size and light weight, they exhibit
unusual and interesting properties.

4. Construction of Infrared Plastic Solar Cell
The solar cell created is
actually a hybrid, comprised of
tiny nanorods dispersed in on
organic polymer or plastic.
Nanorods are made of
cadmium solenoid.
This layer of round 200
nanometers thickness is
sandwiched between
electrodes.
The electrodes are coated with
aluminum.

5. Working of Infrared Plastic Solar Cell
 A layer only 200 nanometers thick is sandwiched between electrodes.
 Nanorods in the plastic solar cell acts like wires when they absorb light
of specific wavelength they generate an electron and electron hole
vacancy in the rod that moves around just like an electron.
 The sunlight passes through the transparent plate and electrode is
absorbed by the semiconducting donor and acceptor material in the
photoactive layer.
 When Nanorods absorb light they generate an electron and an electron
hole. Electron is collect by aluminum electrode. The hole is transferred
to the plastic and conveyed to the electrode, to creating a current.

6. IMPROVEMENTS
Better light collection and concentration employed in the
solar cells.
In plastic cells Nano rods closely packed and transfer
their electrons more directly to the electrolyte.
They also hope to tune the Nano rods to absorb different
colors to span the spectrum of sun light.

7. APPLICATIONS
1. In remote area, we require lots of electricity so we
can use plastic cells as a poster of power solar panel
by connecting number of cells.
2. These cells can also be used in portable devices by
spraying it on those devices as a paint.
3.Solar plastic cells can also be used in mobile phones
or other wireless devices.

Hydrogen Powered Car With Plastic Solar Cells On
Top:
Hydrogen car painted with the film could convert
solar energy into electricity to continually recharge the
car’s battery. Solar plastic cells can also be used in
charging electrical hydrogen cars by placing plastic
cells with proper connection on the top of those cars.

In many lighthouses and most buoys are now powered by
solar cells.

10. ADVANTAGES
Plastic solar cells are quite a lot useful in the coming future. This is because of
the large number of advantages it has got. Some of the major advantages
are:
 They are considered to be 30% more efficient when compared to
conventional solar cells.
 They are more efficient and more practical in application.
 Traditional solar cells are bulky panels. This is very compact.
 Conventional solar cells are only used for large applications with big
budgets. But the plastic solar cells are flexible as they can be even sewn into
fabric thus having vast applications.
 Flexible, roller processed solar cells have the potential to turn the sun’s
power into a clean, green, consistent source of energy.

11. LIMITATIONS
They are very costly.
Relatively low life span as compared with pv cell when
continuously exposed to sunlight.
It requires higher maintenance and constant monitoring.

12. CONCLUSION
Plastic solar cells help in exploiting the infrared
radiation.
More effective when compared to conventional solar
cells.
They can even work on cloudy days.
Though at present cost is a major drawback, it can be
solved in the near future.

13. FUTURE SCOPE
Improve the efficiency of plastic solar cell.
Improve the time span of plastic solar cell for widely use.
Decrease the cost of manufacture of plastic solar cell.
Research is on to fabricate thin film InAs/GaAs quantum
dot solar cell which have alternatively low cost, light
weight flexible using the same layer transfer scheme.
