- France and China have developed Photovoltaic roads
- Photovoltaic highway is constructed using solar panels which have thin sheet of transparent concrete on top of them, protecting the surface.
- It has wireless charging systems for electric vehicles (EVs).
- The photovoltaic panels of the highway are built to transfer energy to electric vehicles passing on top of them.
- The road has three layers viz. bottom layer which is insulator to prevent moisture from getting to photovoltaic devices in middle layer, and top layer has transparent concrete.
