WHAT IS SOLAR PANEL?
EVERY ONE KNOW THE ANSWER, IT’S THE COMPONENT, THAT CONVERT THE
SUNLIGHT INTO ELECTRICAL ENERGY.
 |
| SOLAR PANEL |
Sunlight is composed of miniscule particles
called photons, which radiate from the sun. As these hit the silicon atoms
of the solar cell, they transfer their energy to loose electrons, knocking them
clean off the atoms, and the electricity start flowing. The photons could be
compared to the white ball in a game of pool, which passes on its energy to the
colored balls it strikes. Main disadvantage of this cells. that it require
specific area for implantation and continues expose to the light.

WHAT
IF SOLAR PANEL GO Transparent
TRANSPARENT SOLAR PANEL
·
Its work same as the simple solar cells but we can see
through it.
·
Main advantage of this cells is That, it can be used as a
simple glass.
Introduction
of TRANSPARENCY :
Researchers of MIT,
are making transparent solar cells that
could turn everyday products such as windows and electronic devices into power generators without
altering there look.

HOW TO
MAKE CELL TRANSPARENT???
GREPHENE
IS USED for
transparency in TRANSPARENT SOLAR SCREENs. The solar cells contain the layer of
GRAPHENE and because its single layer thick(one atom), no one can detect its
presence in simple glass.
• GRAPHENE is a form of carbon consisting of planar sheets which are one atom
thick, with the atoms arranged in a honeycomb-shaped lattice.
•
Material
used in transparent solar cell is GRAPHENE.

PROPERTIES OF GRAPHENE:
- — Graphene's band gap can be tuned from 0
to 0.25 eV
- — Graphene displays remarkable electron mobility at room
temperature 15000 cm2⋅V−1⋅s−1
- — Graphene is the only form of carbon (or solid material) in which
every atom is available for chemical reaction from two sides ( GOOD
CONDUCTIVITY )

Mechanism For TRANPARANCY
— Three years ago, a team in MIT’s Organic and Nanostructure
Electronics Laboratory began to tackle the problem using a different approach
to make it transparent. Then a professor suggested the idea, for achieving the fully transparent SCREEN
— Transparent Luminescent Solar
Concentrator (TLSC),

It’s the type of screen made on the theory of TLSC
• THE SUBSTRATE IS 90 %
TRANSPARENT.
• LOW COST and NON TOXIC
MATERIAL

WYSIPS COMPONENT
Ø In MARCH 2015 at Mobile World Congress in Barcelona, Kyocera is
showing off a concept phone that uses its own display to convert the sun's rays
into juice for its battery.
Ø The prototype employs a transparent photovoltaic layer that can be
placed on top of or beneath the touch screen.

Self-Charging Cell Phone Screens :
Researchers at the University of
California Los Angeles (UCLA) are taking a similar approach,
while researchers at the University of Cambridge are weaving solar
cells into organic light emitting diode (OLED) displays, where they can capture
light leaked from the edges of the OLED elements as well as from outside the
phone.

Advantage
of Transparent solar cells
- — Because its transparent it can be placed in Electronic devices.
- — Photo voltaic power can be generated at any point of earth by sun
- — Overcome the problem of specific large area requirement.
- If we use this on windows , it can possibly generate more power then
conventional pane
- It can also be used in ambient light source.
- — It also last for more then 20 years without degradation.
DISADVANTAGE
OF TRANSPARENRENT SOLAR CELL
- — It
produce low amount of energy when it used with electronic devices.
- — Its
unable to absorb all the light ( transparency and efficiency mutually
exclusive.
- — Reflection
and absorption losses , Low active area.
