3.  It is intriguing to think of photovoltaic (PV)
elements based on thin plastic films. The
flexibility offered through the chemical
tailoring of desired properties, as well as the
cheap technology
 The mechanical flexibility of plastic materials
is welcome for all PV applications onto curved
surfaces for architectural integration

4.  Solar energy is, simply, energy provided by the
sun. This energy is in the form of solar radiation,
which makes the production of solar electricity
possible.
 Electricity can be produced directly from
photovoltaic, PV, cells. (Photovoltaic literally
means “light” and “electric.”) These cells are
made from materials which exhibit the
“photovoltaic effect” i.e. when sunshine hits the
PV cell, the photons of light excite the electrons
in the cell and cause them to flow, generating
electricity

5.  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

6.  Nano-technology is the
engineering of functional
systems at the molecular
scale
 Offers better built, longer
lasting, cleaner, safer and
smarter products for the
home, For medicine and for
industries for ages
 we can introduce Nano-
technology that is Nano-
particles into the solar PV
cells.

7. Infrared radiation is electromagnetic
radiation (i.e. light) that has a longer
wavelength (shorter frequency) than
optical (visible) light
Near Infrared (NIR): Wavelengths
ranging from 0.74 micrometres to 5
micrometres.
Mid Infrared (MIR): Wavelengths
ranging from 5 micrometres to about
35 micrometres.
Far Infrared (FIR): Wavelengths
ranging from about 35 micrometres to
300 micrometers

9.  The most common type of solar cells are photovoltaic
Cells (PV cells)
 Converts sunlight directly into electricity
 Cells are made of a semiconductor material (e.g..
silicon)
 Light strikes the PV cell, and a certain portion is
absorbed
 The light energy (in the form of photons) knocks
electrons loose, allowing them to flow freely, forming
a current
 Metal contacts on the top and bottom of PV cell
draws off the current to use externally as power

11. • These are photovoltaic (PV) cells based on
crystalline silicon.
• It absorbs visible sunlight and transferred to
the semiconductor material.
• This energy knocks electrons to flow freely,
which results current.
• Current is drawn from the metal contacts in
PV cell

12.  Amorphous Silicon solar cell
 Bio hybrid solar cell(a-Si)
 Buried contact solar cell
 Cadmium telluride solar
cell (CdTe)
 Concentrated PV cell (CVP and
HCVP)
 Copper indium gallium selenide
solar cells (CI(G)S)
 Crystalline silicon solar cell (c-Si)
 Dye-sensitized solar cell (DSSC)
 Gallium arsenide germanium
solar cell (GaAs)
 Hybrid solar cell
 Luminescent solar
concentrator cell (LSC)
 Micromorph (tandem-cell using
a-Si/μc-Si)
 Monocrystalline solar cell
 Multi-junction solar cell (MJ)
 Nanocrystal solar cell
 Organic solar cell (OPV)
 Perovskite solar cell
 Photo electrochemical
cell (PEC)
 Plasmonic solar cell
 Plastic solar cell
 Polycrystalline solar
cell (multi-Si)
 Polymer solar cell
 Quantum dot solar cell
 Solid-state solar cell
 Thin-film solar cell(TFSC)
 Wafer solar cell, or wafer-
based solar cell (synonym
for crystalline silicon solar
cell)

14.  In conventional solar cell it is observed that only 35% of the
suns total energy is being used
 The conventional solar cells are not so favorable on cloudy
days
 In order to overcome these disadvantages we use INFRARED
PLASTIC SOLAR CELL

15.  plastic solar cell can turn the suns power into electric energy
even on a cloudy day.
 The plastic material uses nanotechnology and contains the
1stgeneration 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

17.  It requires
semiconductor nano
rods (7 nm by
60nm).
 The heart of a solar
cell is a 200-nm-
thick film
 It consists of
cadmium selenide
(CdSe) nano rods
and blended with
P3HT(poly-
3hexylthiophene)

19. • When Nano rods 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, creating a current.

20.  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.

23. 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 CELLS
Constructed using Nano-

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

24.  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 feasible 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

25. Hydrogen car painted with the film could convert solar
energy into electricity to continually recharge the car’s
battery

26.  They are very costly.
 Relatively shorter life span when
continuously exposed to sunlight.
 It requires higher maintenance and constant
monitoring.

27.  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.
