Crystal Growth of Silicon for Solar Cells

Abstract

Fundamental understanding of crystal growth behaviors from Si melt is significant for the researchers, who are involved in the development of crystal growth technologies. In the light of Si crystals for solar cells, it is imperative to improve the crystal-quality of Si-multicrystal ingot grown by casting, because it is widely used for solar cell substrates in the present and future. Faceted dendrite has unique structural features and has a potential to be used for controlling the crystal structure in Si-multicrystal ingots. In addition, basically, its growth behavior is fascinating. In this chapter, the growth mechanism of Si faceted dendrite will be described with recent experimental results.
