I'm hoping suncells and batteries will become really good, so it's possible to drive your house electricity on only the sun. Would be truly liberating.

This at scale with a room temperature superconductor.
it is already something you can do, if you put enough solar panels
Yeah I guess but then you need a big roof probably. I was hoping they could be more efficient to double their performance, so half the space could be used (and possible half the cost).
But we will see :)
There is not much room for optimization left. Best solar cells get close to 23% efficiency, apparently the current theoretical maximum is a little over 30%.
