How to Make Solar Cells

The world needs very much the use of alternative energy, not because of the vacuum, but because of the severity of the damage discovered by all countries of the world by the use of traditional means of energy, the disadvantages of this type of energy it is expendable energy, in addition to polluting the environment that results from The use of these materials, as a result of the burning of this energy, which emit many of the harmful gases very large, and this would destroy the environment very large, and traditional energy sources cause conflicts and much in the world because of their lack of availability in all regions , Who has on who He owns a large and important part of the world and controls it and controls its economy.

And this is happening now, in addition to the fact that the sale of petroleum products provide a large income to the countries that sell them. One of the most prominent types of alternative energy known as solar energy, which is used in the energy production of electricity, and this is by converting solar energy into electrical energy. This is not automatic, but solar energy is converted into electrical energy by what is known as solar cells.

 Solar cells are made primarily of silicon, which absorbs the falling rays on the cell, and then converts them into electrical energy. Where silicon is used in the industry because of its high availability in nature, in addition to their prices very simple, and the process begins with the choice of pure silicon, which is exposed to heat and delivery to the state of fusion by raising the temperature of a very large, and then is brought boron, And then add it to the molten silicon to form the positively charged semiconductor, and then the process of formation through the process of casting in special molds and through the process of the roads as well, where it comes from the stage of cutting in the form of slides and characterized by lightning and then clean these segments well, In special furnaces so that scatters phosphorus on the edge of the slide, and this part consists of negative.
