Solar cell

A solar cell is a device that transforms the rays of sunlight into electricity. Longer term technically for a solar cell is a solar cell.

The term "photo" derives from the Greek word for "light", and the term "Burkina"comes from the word "v" which means"force electrical".a"cell" is a small container or a container containing electrodes that generate power.

Thus, a solar cell is a container that creates electrical force, through the light.

Considering that a solar cell can produce electricity from any light source, its use is the collection of solar energy from the Sun.

-How a solar cell works

The solar cell works as follows:

Photons (which are particles of light in the sun rays) reached the surface of the solar cell and are absorbed a semiconductor, such as Silicon.

These photons (bit of sunshine) knock electrons loose in atoms in semiconductor .the photons and electrons push along, leaving a "gap" in the atom. Another electron then pulled from an adjacent atom to fill the gap.Thus, an electric flow is generated.

The simplicity of this is that an atom has an extra electron, and another atom one is missing.This is called a "potential difference."Nature, wishing to remain balanced, tries to even things out by pulling an another electron Atom neighbor.

A solar panel is composed of a group of solar cells which are linked together to produce the quantity desired of electrical energy.

A group of interconnected solar cells can also be called a .ainsi "module" the terms "solar panel" and "solar module" are synonymous with each other, and essentially mean the same exact thing."Solar panel" is the more common term, and "solar module" is the technical term.

Can use solar panels individually or may relate more to generate more electricity.When a group of solar panels is connected between them, it is called a "solar".More solar panels are included in a solar array, the more energy than they produce.

Solar is a clean energy source that is practically illimitée.Je say "almost limitless", because the sun itself does hard step éternellement.Mais we don't have to worry about that for the next few billion years.

As solar energy is a clean energy source that has existed for decades, one might wonder why its not used plus.La answer to this lies partly in the cost of production of solar panels, as well as the efficiency of solar panels.

We are currently in the second generation of solar panel technology and verging on the troisième.beaucoup has changed since the first panels one génération.Solar are becoming a source of viable clean energy.

First solar cells were relatively large and bulky compared to our actuels.Compte models of energy and the equipment needed to produce the and the amount of energy that they actually produced, it was more costly to use solar energy to use fossil fuels.The only exception was in places where fossil fuels little or none were available, as in space.

With cells solar second generation, we tried to tackle this problem exact.Nous tried to improve manufacturing techniques to reduce costs, the materials and the energy necessary for the production of solar cells.

Recently, major advances have been made in the production of solar cells which reduces production costs.

A contribution to the area has been developing techniques for coating of glass or ceramic material with very thin layers of substances semi - conductive .This helped produce solar panels using only a fraction of the semi-conductive material which was more tôt.La production of solar panels on this second generation technology is called "Thin Film technology."

Third-generation solar technologies are running currently studied and developed .the ' goal is to further improve the power of the solar cells (while maintaining minimum production costs) in which case 30-60% of light from the Sun by pressing the panels will be converted into electricity.(Currently, solar panels convert only about twenty per cent).

But apart solar technology third-generation cell solar second generation is effective enough to make viable solar technology - and a host of new products operating solar have hit the consumer market.

Based on the solar calculators have been around for some time now, we have all given leur.Nous even saw a few other devices of nouveauté.Mais only in solar devices years come into serious and practical use.

The last two years, in particular, saw a virtual explosion of solar devices by pressing the marché.Lampes solar handheld (I often wandered what use they were), radios operating solar and, recently, solar battery chargers.

One can also find a wide range of portable solar chargers and panels, which is lightweight and portable, yet capable of providing a decent amount of power, even the most solar distants.Chargeurs become a standard part of emergency kits and desert survival kits.

This is the result of developments in the technology of solar cells and solar era arrived.
