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.
