1. APPLICATION OF 3D
GRAPHENE IN
SOLAR
TECHNOLOGY

2. INTRODUCTION
 There nothing else than a solution for
increasing demand of power.
 Solar panels are one of the most popular
tool for renewable energy.
 Solar technology with the nanomaterial
3D Graphene as the alternative.
 They are increasingly being used
particularly in warm countries, and more
Eco-conscious countries like Germany.

3. WHAT IS 3D GRAPHENE?
 Regular graphene is a famously two-
dimensional form of carbon.
 A unique 3D version with a honeycomb-
like structure was discovered in 2013.
 The thickness and chemical property
differs a lot when compared with a regular
graphene.

4. FORMATION OF 3D GRAPHENE
It is a combination of lithium oxide with
carbon monoxide in a chemical reaction that
forms lithium carbonate (Li2CO3) and the
honeycomb graphene.

6. CONSTRUCTON OF 3D GRAPHENE
SOLAR CELLS
 3D graphene cells are encapsulated
between films of polymer protecting the
cells from the effect of moisture which
would corrode the electrical connections.
 Cells are connected in series by flat
strips of copper soldered onto the front
face of one cell and the rear face of the
next.

7. A frame of aluminium is fitted
around the edges to protect and
stiffen the panel.
Platinum can be replaced by 3D
graphene.
Flexible panels can be made by
combining nano porous
germaniun and graphene of 3D
structure.

8. RESEARCH ON 3D
GRAPHENE
 Researchers at MIT are studying solar cells
made from single molecule thick sheets of 3D
graphene and materials such as molybdenum
di selenide.
 Researchers at Princeton University have
developed a solar cell that almost eliminates
losses due to reflection of light.
 They use a 30 nanometer thick gold nanomesh
with 3D Graphene along with an active layer
thinner than the wavelength of light.

9.  Researchers at MIT have developed a solar
cell using 3D Graphene coated with zinc
oxide nanowires.
 Researchers at the Nies Bohr Institute have
determined that sunlight can be concentrated
in nanowires due to a resonance effect.
 Researchers at Los Alamos National Lab
have demonstrated a solar cell that uses a
3D Graphene quantum dot.

10. ADVANTAGES
Increase in efficiency(78%)of energy.
Eco-Friendly.
Reduced installation cost.
It has longer life span and can be
easily replaced.
Panels can be made flexible.

11. APPLICATIONS
Coating existing roofing materials with 3D
Graphene cells then enough energy could be
captured to power almost the entire house.
3D Graphene solar cells would also help
provide electricity for rural areas or third
world countries.
Flexible layers of Nano porous germaniun
and graphene of 3D structure to produce
lightweight solar cells for mobile
applications.

15. CONCLUSION
 Solar power is looking more and more
attractive, as other power generation methods
such as fossil fuels and nuclear power come
under increasing scrutiny.
 Nano materials (“3D Graphene”) solar cells
shows special promise to both enhance
efficiency of solar energy conservation and also
reduce the manufacturing cost.
 It increases efficiency by increasing the
absorption of light as well as the overall
radiation-to-electricity would help preserve
the environment, decrease wastage, provide
electricity for rural areas, and have a wide array
of commercial applications due to its
capabilities.
