Designed by Johgoh Lee, the Invisible Streetlight is a solar powered street light that imitates leaves and can be hidden among natural plants on the sides of streets. Comprising of a double injection of silicon, aluminum materials and a photo capacitor, these keep glowing all night long. The photo capacitor is an electricity storage device proofing more efficiency than silicon based solar cell in low light.
The standard photovoltaic cells are dependent on a battery to store the electrical power converted from light, a photo capacitor is combining photoelectric and storage functions in a single unit. Moreover these lights blend beautifully with the leaves, giving a spectacular view and they save a tremendous amount of energy during the day, emitting light only at night.
