Как выглядит солнечная панель?

Все знают, что такое фотоэлектрическая панель и для чего она используется., но мало кто мог сказать, как он работает и из каких материалов состоит.

Фотоэлектрическая энергия, несомненно, является одним из наиболее перспективных альтернативных источников энергии..

It is generated by solar panels, инструменты, преобразующие солнечные лучи в энергию, полезную для человека, and are used today in a variety of fields of use: from installation on the roofs of houses to provide heat and electricity, to use on spacecraft, to which they can provide energy even for decades.

But what does a photovoltaic panel look like? And how does it actually work?

There are two main types of panels:

1. photovoltaic panels, also called “солнечный” panels, are used to generate electricity from sunlight;
2. solar thermal panels, which instead use sunlight to heat water.

Today we will discuss the first type, PV.

They are composed of multiple photovoltaic cells, small electronic devices arranged side by side and connected together to form the heart of solar power generation systems.

Each is composed of several elements: a conductive metal base and protective glass enclose two semiconductor plates, P-type and N-type, and several conductive metal contacts.

The two sheets are composed more of silicon, a material that can act as a conductor or an insulator depending on the situation.

Кроме того, boron is used to create the P-type plate: by mixing it with silicon, unstable gaps are created carrying positive charges; the N-type plate, on the other hand, is created by mixing silicon and phosphorus. This time, Однако, one electron remains free carrying negative charges.

When overlapping the two types of silicon, some electrons come together forming an electric field.

Sunlight disrupts the system’s bonds: by connecting wires to the cell’s contacts, excess electrons and gaps tend to come together, thus creating an electric current.
