Nanotechnology offers groundbreaking advancements in the field of solar energy. Traditional solar cells are often limited by their inefficiency and high production costs. However, the use of quantum dots and perovskite materials can significantly enhance the efficiency of solar cells. Quantum dots can be tuned to absorb different parts of the solar spectrum, optimizing the light absorption process. Perovskite solar cells, on the other hand, are easier and cheaper to produce while offering remarkable efficiency improvements compared to traditional silicon-based solar cells.
