Researchers at Stanford University in the United States have been working hard to improve the efficiency and longevity of solar panels in order to make solar energy a more mainstream and easy-to-use environmentally friendly energy source. The nanoshell (a hollow cylinder made of silicon material) is the latest achievement of Stanford scientists. In the development of this material, they first immersed the crystalline material in silicon, and then used hydrofluoric acid to make the cylinder's The middle part is eroded to create more efficient light-absorbing properties.
