Plasmonic solar cells are a type of solar energy technology that utilizes the unique properties of plasmonic materials, which can enhance light absorption. These materials, often made from metals like silver or gold, can concentrate light at specific wavelengths, increasing the efficiency of solar cells. By integrating these materials into traditional solar cell designs, researchers aim to capture more sunlight and convert it into electricity. The main advantage of plasmonic solar cells is their potential to improve energy conversion rates without significantly increasing costs. This technology is still under research, but it holds promise for creating more efficient and affordable solar energy solutions in the future.
