A battery swap while on the move might be more efficient/faster then a charge on the move. (But it would be nice if the next-gen solar panels installed on a car would be efficient enough to provide enough power for a car drive)

Model S has a 310KW motor. Assume you only run it at 10% of rated power when cruising, and that's 31KW of power draw. More than that, of course, since the motor controller won't be perfectly efficient.
No way you can run a consumer vehicle on solar panels built into the body.
I'd pay extra for such solar panels in the roof.

And I doubt solar panels would ever be used for charging the whole car in a very significant way, even if they had 80% efficiency.
