What is Single Crystal Silicon?
Single crystal silicon is a type of silicon used in solar cells, and it has a well-ordered crystalline structure made up of a single crystal. The crystal is typically obtained through the Czochralski growth technique, where a seed crystal is dipped into molten silicon and slowly pulled out to grow a single crystal ingot.
