Seems solar cells have their own Moore's law at work.

I think this is a special case of Wright's Law.
Even for semi-conductors, Wright's Law has described price changes better than Moore's Law.

For whatever reason, I can never remember the name of this and always have to search The Core for "Moore" to find it again.
