The final product, produced by LLP «KazakhstanSolarSilicon», is a photovoltaic cell - a special kind of a semiconductor diode, which is capable to convert visible light, infrared and ultraviolet radiation into electrical energy. Energy conversion is based on the photoelectric effect, which occurs in inhomogeneous semiconductor structures when exposed to sunlight. In the manufacturing process using as a basis (substrate) multicrystalline silicon wafers are subjected to various kinds of physical and chemical treatment to achieve the stated performance and reduce losses.
