ABSTRACT:

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. INFRARED POWER
• Plastic solar cells are not new, but the existing
solar cells which are of conventional type
could only harness sun's visible rays i.e. only
half of the sun's radiation.
• This process of harnessing the infrared
spectrum is done by researchers by combining
specially made plastic which will detect
infrared spectrum.

6. • The plastic solar cell created by
Berkeley research group is actually a
hybrid, comprised of tiny Nano-rods
dispersed in an organic polymer or
plastic.
• The thickness, 200 nano-metres --a
thousandth the thickness of a human
hair -- is a factor of 10 less than the
micron- thickness of semiconductor
solar cells. when nano-rods absorb light
of a specific wavelength, they generate
an electron plus an electron hole--a
vacancy in the crystal that moves
around just like an electron.
DESIGN

7. COST AND EFFICIENCY
• They cost about 10 times more than the traditional, semiconductor solar cells that are
in use now. today's high efficiency solar cells require very sophisticated process
inside a cleaning room and complex engineering to make the semiconductor
sandwiches and because they are baked inside a vacuum chamber, their size should
be relatively small.
• whereas these hybrid solar cells can be produced in laboratory beaker without any
requirement of clean rooms and vacuum chambers ,which means they are very cheap
and can be made easily rather than conventional solar cells.
• The plastic solar cells are flexible and cannot be broken easily as conventional solar
cells. Thus the plastic solar cells can be made more efficient, cheaper and its life span
can be increased by using latest techniques in the field of nanotechnology.

8. APPLICATIONS
 The plastic formulations also open the possibility of printing solar cells onto
various surfaces, much as how ink is printed on a newspaper, because of this
property they can be painted anywhere and can be used as solar cells for
converting sun's radiation into electricity.
 The painted screens can be used to power portable electronic goods like cell
phones, iPods, laptops and pocket calculators etc. anywhere and everywhere.
 Ultra high efficient plastic solar cells can even work under low light conditions and
also under artificial light along with the increased wavelength region.
