Solar cells bonded to the car directly require some sort of clear resin, epoxy, or polymer. This usually only lasts about a year before it starts to break down from UV damage. Not worth it at all!
The sail boating guys experimented with the flexible solar panels, and they almost never make it 2 years even, and those use a much thicker top substrate. Problem is it's almost impossible to find a plastic that can pass the wavelengths needed to make PV work, and reject the high-energy UV that breaks apart the molecules in the plastic. This is why all real solar installations are using tempered glass as a top substrate.
