Why is silicon used in solar cells? Silicon is the most popular semiconductor material used in solar cells, representing nearly 95% of the modules sold today. It is also the second most ample material on Earth (after oxygen). In the old days, silicon solar cells used to be rather expensive, as very high-quality silicon was required to make them.

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.
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.
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.
Each cell is composed from two layers of silicon. However, the silicon is not pure - the top layer has been mixed with an element with easily freed electrons ('n-type') such as phosphorus and the bottom layer has been mixed with an element which has free places for electrons to occupy ('p-type') such as boron.
The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.
