Murphy's law would dictate that is would become opaque at the wrong moment.

The flexible PV panel doesn't generate enough electricity to provide any meaningful power to the static battery pack. There are prototype PV technologies that may supercede the one being used by Toyota currently. There are rigid PV panels that provide about 3 times the amount of power than the type being used by the 2010 Prius but they are experimental ( NASA used them for the Mars robotic explorer) and they are custom made and are currently not availabe as a mass produced item. The new Hi powered PV panels generate electricity buy using multiple semi translucent PV panels which are sandwiched on top of each other. Each layer is only sensitive on a particular spectrum of light. So while each layer is no more powerful than a regular PV panel - since the layers are sandwiched on top of each other the PV takes only one third the surface area as a non-sandwiched single layer PV panel. The last I heard, NASA was testing a 4 layers PV solar cell technology and was getting about 33% energy efficiency. |
