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.
During the past few decades, crystalline silicon solar cells are mainly applied on the utilization of solar energy in large scale, which are mainly classified into three types, i.e., mono-crystalline silicon, multi-crystalline silicon and thin film, respectively .
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.
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.
Commercially, the efficiency for mono-crystalline silicon solar cells is in the range of 16–18% (Outlook, 2018). Together with multi-crystalline cells, crystalline silicon-based cells are used in the largest quantity for standard module production, representing about 90% of the world's total PV cell production in 2008 (Outlook, 2018).
Multi and single crystalline are largely utilized in manufacturing systems within the solar cell industry. Both crystalline silicon wafers are considered to be dominating substrate materials for solar cell fabrication.
