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.
Principle
Principle-2
Characteristics
1. Power source without the money, taken from an inexhaustible clean energy without pollution.
2. The daily generating capacity and is proportional to the strength of shot.
3. Light weight, simple structure, suitable for small scale installation, with a wide range of use.
4. 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.

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.
