The document discusses implementing carbon nanotubes in solar panel technology. It begins with an introduction to solar energy and the current materials used in solar panels. It then provides a history of carbon nanotubes, their advantages and disadvantages, and how they can be used to increase solar panel efficiency. Specifically, carbon nanotubes can increase efficiency up to 80% due to their thermal and electrical conductivity properties. The document concludes that carbon nanotubes are promising for miniaturizing electronics and creating more efficient solar panels.

3. Introduction
 Solar energy is capturing the solar radiation and coverting
it into electricity.
 Presently solar panel is made up of Silicon or Gallium Arsenide
(GaAs) material which has low efficiency and high cost.
 So introduction of carbon nanotubes in solar panel
technology will help us to eliminate this problem.
 The electrical, machanical and thermal properties of
Carbon nanotubes “CNTs” are dependent on their
diameter .

5. Carbon Nanotubes
 Carbon annotubes were invented in 1991 by the japanese
electron microscopist “ SUMIO IIJIMAA ”.
 IIJIMA discovered Multi walled carbon nanotubes (MWCNT) in
arc burned rods.
 1993 Bethune and Iijima independently discover Single walled
carbon nanotubes(SWCNT).

 Carbon nanotubes are made of carbon.
 Carbons are available in many allotropes form which depend on the
structure arrangement of carbon.
 Carbon nanotubes are fullerene-related structures which consist
of graphene cylinders closed at either end with caps containing
pentagonal rings.
 CNTs is important for nanotechnology,electronics,optics and other field
of technology.

7. Why carbon nanotubes used?
 The solar filmed photovoltaic panels made of amorphous silicon
The production methods are complex, but less energy intensive
then crystalline solar panels.
 So introduction of carbon nanotubes in solarpanel technology by
using solar energy will help us to eliminate this problem.
 CNTs are used in the technology of solar panels to increase the
efficiency of the solar panel up to 80%.

9. Single Walled Carbon Nanotubes
 A single walled carbon nanotubes (SWNT) is made from
single atomic layer thick sheet of graphite (called graphene)
rolled into a seamless cylinder.

 Most single walled (SWNT) have a diameter of close to 1 nanometer
with a tube length that can be many millions of times longer.
Single walled nanotubes are an important variety of carbon nanotubes
because they exhibit electric properties that are not shared by the multi
walled carbon nanotubes (MWNT) variants.

11. Multi Walled Carbon Nanotubes
Multi walled nanotubes (MWNT) consist of multiple rolled
layers (Concentric tubes) of graphite.

17. Advantages
 It will be increase the efficiency.
 Extremely small and lightweight.
 Making them excellent replacements for metallic wires.
 Are resistant to temperature changes, meaning they function
almost just as well in extreme cold as they do in extreme heat.

18. Disadvantages
 Despite all the research, scientists still don't understand exactly how
they work.
 Extremely small, so are difficult to work with.
 Currently, the process is relatively expensive to produce the
nanotubes.
 At the rate our technology has been becoming obsolete, it may be a
gamble to bet on this technology.

19. Conclusion
 Carbon nanotubes are the next step in miniaturizing electronic
circuits , replacing silicon transistors and diodes , which are fast
reaching the theoretical limits of size and speed of operation.
 Using CNTs, nanochips can be made with entire circuits on it. Ideal
diodes can be made from CNTs, resulting in highly efficient
electronic circuits.
