What is the solar road?

Colas, world leader in transport infrastructure, has unveiled Wattway, the Solar Road. The fruit of five years of R&D in a partnership with the French National Institute for Solar Energy, this major innovation gives an entirely new function to roads, that of producing renewable energy.

Which solar cells can be used in PV pavement?

Moreover, some emerging solar cells, such as dye-sensitized solar cells (DSSC) , organic solar cells (OSC) , and perovskite solar cells (PSC) , might be promising and competitive in the PV pavement field with lower cost in the future.

How to protect solar cells from fragmentation?

At the same time, the compression force from the top layer ought to be homogeneous to protect the solar cells from fragmentation, and it requires more advanced sealing technologies and materials to alleviate the impact caused by moisture. Poor heat dissipation induces an efficiency decrease and may accelerate the aging process of modules.

What type of semiconductor is a solar cell?

A solar cell is composed of a P-type semiconductor and an N -type semiconductor, while the P-N junction is formed at their interface . When the solar cell is exposed to sunlight, the electrons will receive the energy from photons and move toward the N -type region, making the N -type region negatively charged.

What is solar road surfacing?

It is the world’s first photovoltaic road surfacing solution that generates electricity from clean and renewable solar energy, while providing a safe surface for all vehicular traffic. Since the launch of this solar road solution, about 50 pilot projects around the world have demonstrated Wattway ’s robustness.

Are SR3 solar road panels weather resistant?

As mentioned in Section “Physical models of PV pavement and solar road”, Brusaw et al. have conducted the environmental and mechanical testing on the SR3 prototypes, indicating that all the solar road panels were resistant to extreme weather and moisture conditions, and the external heavy loads .
