Photovoltaic module

Photovoltaic modules or solar panels are devices that are used to capture the energy of the sun's light. Photovoltaic solar panels contain a set of solar cells that convert light into electricity. It is called solar because the sun is one of the strongest energy sources for this type of use. Solar cells are sometimes called photovoltaic cells, and photovoltaics literally means "light-electricity". Solar cells have the photovoltaic effect to absorb the sun's energy and cause electrical current to flow between two charged layers in the opposite direction.

Types of photovoltaic cells

The photovoltaic cells are responsible for converting solar radiation into electrical energy in the form of direct current. Photoelectric cells are an indispensable element for this type of renewable energy.

There are different types of photoelectric cells depending on the nature and characteristics of the materials used. The most common type is the crystalline silicon cell (Si). This material is cut into very thin disc-shaped, monocrystalline or polycrystalline sheets, depending on the manufacturing process of the silicon bar.

Types of photovoltaic panels

In the market there are several types of photovoltaic solar panels for domestic use. The most common types are monocrystalline photovoltaic panels, polycrystalline solar panels and thin-film solar panels.

Around 90% of the photovoltaic technology is based on the use of some silicon variation. In the case of solar panels intended for domestic use, this percentage is even higher.

The main difference between the different types of photovoltaic panels is the purity of the silicon used. The purer the silicon, the better aligned its molecules are, and the better it converts solar energy…

Photovoltaic Solar Energy

Photovoltaic Solar Energy

Solar photovoltaic energy consists in the direct transformation of solar radiation into electrical energy. This type of energy is often referred to directly as photovoltaic energy.

This transformation into electrical energy is achieved by taking advantage of the properties of semiconductor materials through photovoltaic cells. The base material for the manufacture of photovoltaic panels is usually silicon. When sunlight (photons) hits one of the faces of the solar cell, it generates an electric current. This generated electricity can be used as an energy source.

Photovoltaic panel structure

Photovoltaic panel structure

The most important part of a photovoltaic module is the set of photovoltaic cells that are responsible for the transformation of solar radiation into electrical energy. The rest of the elements that are part of a solar panel have the function of protecting and giving firmness and functionality to the whole.

The photovoltaic cells are encapsulated with reinforced glass and several layers of plastic material. Subsequently, all this set is reinforced by forming an outer frame with aluminum metal profiles.

The photovoltaic solar panels that are used at present are formed of the following…

Monocrystalline silicon

Monocrystalline silicon

Monocrystalline silicon is the base material for the silicon chips used in practically all current electronic equipment. In the field of solar energy, monocrystalline silicon is also used to manufacture photovoltaic cells due to its ability to absorb radiation.

Monocrystalline silicon consists of silicon in which the crystalline lattice of the entire solid is continuous, does not break at its edges and is free of any grain limit. Monocrystalline silicon can be prepared as an intrinsic semiconductor that is composed only of very pure silicon, or can be doped by the addition of other elements…

Hybrid solar panel - PVT

Hybrid solar panel - PVT

A hybrid solar panel (more correctly defined as a PVT collector, an acronym P hoto V oltaic and T hermal) is a device that allows the conversion of the energy radiated by the sun partly into electrical energy and partly into thermal energy through the combination of the effect of a photovoltaic module and a thermal solar panel (photovoltaic cogeneration).

Therefore, a hybrid solar panel is composed of a photovoltaic collector to which a heat exchanger is associated, capable of heating a fluid thanks to the part of the solar radiation not converted into electrical energy.

Photollectric cell

In electronics, a photoelectric cell or a photovoltaic cell is an electrical / electronic device that converts the incident energy of solar radiation into electricity through the photovoltaic effect. Photovoltaic cells are the basic components of photovoltaic modules, which are solar panels capable of generating electrical energy from solar radiation. It is therefore the essential basic element for this type of renewable energy.

Compounds of a material that has a photoelectric effect absorb photons of light and emit electrons. When these free electrons are captured, the result is an electric…

Photovoltaic cell. What is it and how it works?

A photovoltaic cell is an electronic device that allows to transform the energy of light into electricity through the photovoltaic effect. It can also be called photocell or photoelectric cell.

Technically, what interests us about light is the photons. Photons are present in all kinds of light but the one that we find most interesting is that which comes from the Sun, solar radiation.

The photovoltaic cell, therefore, is an essential element for the development of photovoltaic solar energy.

Photovoltaic effect

Photovoltaic effect

The photovoltaic effect is the photoelectric effect characterized by the production of an electric current between two pieces of different material that are in contact and exposed to light or, in general, to electromagnetic radiation.

The photovoltaic effect consists of converting sunlight into electrical energy by means of photovoltaic cells. These cells are semiconductor devices made from pure silicon with the addition of impurities of certain chemical elements. Photovoltaic cells are capable of generating electricity in direct current, using solar radiation as a source.

History of solar energy

Within the history of solar energy, in one form or another, solar energy has always been present in the life of the planet being this imprescidible for the development of life. However, the way in which human civilization has exploited it invented new strategies and tools has undergone a long evolution.

Rated voltage

Rated voltage

In electricity, the rated voltage of an electrical device is the voltage that must not be exceeded in normal operation. The nominal adjective is because that tension usually serves to characterize the device, to name it. The nominal value indicates the theoretical or ideal value of anything that can be quantified, as opposed to the real value, which is what is obtained in a given measurement.

Another definition of rated voltage: The rated voltage is the specific potential difference for which a device or installation is designed.

As it is a nominal value it implies that the voltage…

Electrolyte. What is it?

Electrolyte. What is it?

In chemistry, the term electrolyte refers generically to substances that in solution or in the molten state undergo subdivision into ions of their molecules. Substances that do not dissociate are called non-electrolytes.

The term "electrolyte" refers to the ability to conduct electricity through the intervention of ions, a peculiar characteristic of these chemical species. Therefore, an electrolyte constitutes what is called an ionic conductor or, alternatively, a conductor of a second species. Electrolytes are capable of conducting the electric current, once dissolved in solution, precisely…
