The difference between semi-conductors and solar/battery tech is that you are already working at the molecular level with solar panels/batteries and have to change materials to get different results, this is complex as we don't have analytical models of this sort of thing.

With semi-conductors things materials don't need to be changed so much. We are still working with doped silicon (although we do need to make variations with SOI), we are just shrinking something we understand well.
