Silicon

Silicon

Silicon is the starting point of the photovoltaic cycle. It is obtained from sand, which consists mainly of silicon dioxide. As the second most common element in the earth's crust, it is nearly infinitely available.

Silicon is the most common semiconductor material used in solar cells, accounting for approximately 95% of the modules sold today. It is also the second most abundant substance on earth (after oxygen) and the most common semiconductor used in computer chips. A crystalline silicon cell is composed of silicon atoms that bond together to form a crystal lattice.

This grid provides an organized structure that makes the conversion of light to electricity more efficient.

Silicon solar cells now offer a combination of high efficiency, low cost, and long life. The module is expected to last over 25 years and still produce over 80% of its original output.

In a second manufacturing process, high-purity silicon forms a crystalline structure at 2,500 degrees Fahrenheit and then hardens. Next, the crystallized silicon is shaped into prisms. These columns are cut into wafer-thin slices, so-called wafers, using modern wire-cut technology. After cleaning and exhaustive final testing, monocrystalline and polycrystalline wafers form the basis for solar cell manufacturing.

In the third manufacturing step, the wafers are processed into solar cells. They form the basic elements of the resulting solar modules. The cell already meets all technical requirements for generating electricity from sunlight. When exposed to light, positive and negative charge carriers are released within the cell, causing current (direct current) to flow.

Solar Panels

In panel production, solar cells are assembled into larger units or panels. They are framed and Weatherproof. The solar energy module is the final product and is ready to generate electricity. Sunlight is converted into electrical energy in the panel. The direct current thus generated is converted into alternating current by means of so-called inverters and supplied to the public power grid or, if necessary, directly to the house.
