Foreword
In today's society, given that the industry developed
excessive selfish and human thought, extensive use of
non-renewable energy resources, such as: stone Oil,
natural gas, coal, nuclear power, etc.
These energy use will not only destroy the natural
environment nor unlimited Energy, greenhouse effect
and climate in recent years, mankind began to perceive
the use of gravity, so that Began actively looking for a
clean and environmentally friendly energy alternatives
to play this important role.
What is a solar cell
Solar cells are also known
as solar or photovoltaic cells,
is a very direct generation of
optoelectronic thin slices. As
soon as it was light, instant the
output voltage and current.
In physics is known as
photovoltaic
(Photovoltaic,
abbreviated as PV), referred to
as PV.

Power source without the money, taken from an
inexhaustible clean energy without pollution.
The daily generating capacity and is
proportional to the strength of shot.
Light weight, simple structure, suitable for small
scale installation, with a wide range of use.
Prices: current conventional energy prices higher,
as traditional energy costs quickly rise, will
change in the future.
Type
 Single-crystal
silicon
 Polycrystalline
 Amorphous
Single-crystal silicon
Single-crystal silicon cell was
most common, used in power
plants, charging systems, lighting
and traffic signals, Power and
voltage range, high conversion
efficiency, service life.
Polycrystalline
Polycrystalline silicon efficiency
than the single-crystal silicon, due
to the relatively simple process steps,
the cost is also low, compared with
single-crystal silicon power.
The pool is 20% cheaper, so some of the power of
low-power applications are made of polycrystalline
silicon solar cells .
Amorphous
Commercialization of amorphous silicon solar
cells for the current lowest cost solar cells without
encapsulation, the fastest production, production
Product variety and use extensively.

Comparison table
Application
Conclusions
Emergence of solar cells, making
power the means to make, nobody ever
Nature can get sunlight every day but can
be converted into electricity, replaced the
important role of oil, and solar energy
Batteries in the power generation process
is not affected.
