Question

How silicon is extrcted for solar panels?

Answer 1

Boron is a p-type dopant. Its diffusion rate allows easy control of junction depths. ... Gallium-doped silicon is also promising for solar cells, due to its long minority carrier lifetime with no lifetime degradation; as such it is gaining importance as a replacement of boron doped substrates for solar cell applications.

Answer 2

Silicon create a Semi conducter , after doping of P type semiconductor ,e.g. Boron or n type semiconductors e.g. Al.. then silicon is extracted for solar panels
