Silicon solar cell raw materials
In the PV industry, the production chain from quartz to solar cells usually involves 3 major types of companies focusing on all or only parts of the value chain: 1.) Producers of solar cells from quartz, which are companies that basically control the whole value chain. 2.) Producers of silicon wafers from quartz–.

A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.
What is single crystalline silicon?
Single crystalline silicon is usually grown as a large cylindrical ingot producing circular or semi-square solar cells. The semi-square cell started out circular but has had the edges cut off so that a number of cells can be more efficiently packed into a rectangular module.
How are mono crystalline solar cells made?
The silicon used to make mono-crystalline solar cells (also called single crystal cells) is cut from one large crystal. This means that the internal structure is highly ordered and it is easy for electrons to move through it. The silicon crystals are produced by slowly drawing a rod upwards out of a pool of molten silicon.

How are solar cells made?
The majority of silicon solar cells are fabricated from silicon wafers, which may be either single-crystalline or multi-crystalline. Single-crystalline wafers typically have better material parameters but are also more expensive. Crystalline silicon has an ordered crystal structure, with each atom ideally lying in a pre-determined position.
