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.
