2> Description:

• Crystalline Silicon Cells

Crystalline silicon - also known as "solar grade silicon" - is the most abundant bulk material available for solar cell production.

Bulk silicon is categorized according to crystallinity and crystal size in the silicon wafer, ribbon or ingot.

This video offers a much deeper understanding of the solar cell process. It is quite involved and runs for about 20 minutes - so grab a cup of coffee and prepare to be highly informed!

• Mono-crystalline Silicon

A single-crystal silicon - often made using the Czochralski process - mono-crystalline wafer cells are generally expensive.

The expense arises as mono-crystalline wafers are cut from cylindrical ingots.

As a result, the silicon wafers do not entirely cover the surface of a square solar cell module without a substantial waste of refined silicon. Hence most mono-crystalline panels have uncovered gaps at the four corners of the cells.
