The document discusses infrared plastic solar cells. It describes the construction of these solar cells as a hybrid of tiny nanorods dispersed in an organic polymer or plastic layer only 200 nanometers thick sandwiched between electrodes. The nanorods are made of cadmium selenide and act as wires that absorb light and generate electrons and holes. Infrared plastic solar cells could harness invisible infrared light and be five times more efficient than traditional solar cells. They also work on cloudy days due to their ability to absorb infrared light. While costly now, infrared plastic solar cells show promise as a more compact and flexible alternative energy source.

3. • 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 become 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 from sun's radiation.
• Because of their small size and light weight, they exhibit
unusual and interesting properties.
INTRODUCTION

4. Division of sunlight

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

6.  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 collected by aluminum electrode. The
hole is transferred to the plastic and conveyed to the electrode,
to creating a current.
Working of Infrared Plastic Solar Cell

7.  Better light collection and concentration employed
in the solar cells.
 In plastic cells Nano rods are 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.
IMPROVEMENTS

8.  Radio transceivers on mountain tops, or
telephone boxes in the country can often be
solar powered.
APPLICATIONS
 Telecommunication systems:

9.  Hydrogen powered car:
Hydrogen car painted with the film could convert solar
energy into electricity to continually recharge the car’s
battery

10. Ocean navigation aids: many lighthouses and most
buoys are now powered by solar cells.
 Ocean navigation aids:

12. 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.
ADVANTAGES

13.  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.
LIMITATIONS

14.  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.
CONCLUSION

15.  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.
