Nathaniel Said:

Making Solar power?

We Answered:

No.

Solar cells are so expensive because their manufacture is very sophisticated. The silicon is probably built up layer by layer by a vacuum process which ionizes silicon atoms and then "sprays" them onto a special surface. The silicon is also probably "doped" with precise amounts of arsenic, gallium and/or germanium. I suppose it's like making a very large computer chip. Besides, silicon panels aren't all that more efficient than copper oxide sheets. No solar device today is over 20% efficient.
