The scientists are truing so many ways to increase the catch of solar power. They’ve seen that the traditional way of arranging the panels on the roof catches the sun only when it goes directly on them. But, this is so little because afterwards the sun rays are hitting the panels on a different angle and there is a lost of the energy. Using nanoscale 3D structures they’ve come out with 3D solar towers that will be more productive and will trap the most of the solar energy. See more in the link bellow.
