One of the most promising applications of nanotechnology is in the field of solar energy. Nanomaterials such as quantum dots, carbon nanotubes, and perovskite materials can improve the efficiency of photovoltaic cells. For instance, quantum dots can be tuned to absorb different wavelengths of sunlight, increasing the overall efficiency of solar panels. Moreover, nanostructured materials can reduce the amount of light reflected away from the surface, thereby capturing more sunlight.
