 College- I.E.T Khandari, Agra

3.  Low maintenance, long lasting sources of energy.
 Provides cost-effective power supplies for people
remote from the main electricity grid.
 Non-polluting and silent sources of electricity.
 Convenient and flexible source of small amounts of
power.
 Renewable and sustainable power, as a means to
reduce global warming.
 In 2002, the global market for photovoltaic panels
and equipment was valued at 3.5 billion dollars.
Why Use Solar Cells?

4.  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.
 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

5.  Plastic solar cell can turn the suns power into electric
energy even on a cloudy day.
 The plastic material uses nanotechnology and
contains the 1 generation solar cells that can harness
the sun's invisible infrared rays.
 Nano particles called quantum dots are combined
with a polymer to make the plastic that can detect
energy in the infrared
Infrared plastic solar cell

6.  It uses specially designed Nano particles called
quantum dots The quantum dots with a polymer to
make the plastic that can detect energy in the
infrared

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

8.  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
 This electron travels the length of rod until it is
collected by aluminium electrode
 The hole is transferred to the plastic which is known
as a hole carrier and conveyed to the electrode
creating current
Working of Plastic Solar Cell

10. Comparison
PV CELLS
 Made of some special
material called
semiconductors.
 Expensive because of
manufacturing process
 Requires large space,
Efficiency is less
 It won't work under
cloudy conditioned
 It can't harness the
sun's invisible infrared
rays
NANO-SOLAR CELL
 Constructed using Nano-
technology
 Cost is less because less
material is used
 Compact and require less
space, Efficiency is more
 Nano- solar cell that can
turn the suns power into
electricity energy even on
a cloudy days
 It contains the 2nd
generation solar cell that
can harness the sun's
invisible infrared rays

11.  Development of a super thin disposable solar panel poster
 A hydrogen powered car painted with the film could potentially
convert energy into electricity to continually recharge the car's
battery.
 Any chip coated in the material could power cell phone or other
wireless devices.
Applications

12.  They are considered to be 30% more efficient when
compared to conventional solar cells.
 Traditional solar cells are bulky panels. This is very
compact.
 Flexible, roller processed solar cells have the
potential to turn the sun's power into a clean, green,
consistent source of energy.
Advantages

13.  The biggest problem with this is cost effectiveness.
But that could change with new material. But
chemists have found a way to make cheap plastic
solar cells flexible enough to paint onto any surface
and potentially able to provide electricity for
wearable electronics or other low power devices.
Disadvantages

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.
