Multi-junction solar cells are advanced photovoltaic devices that utilize multiple semiconductor layers, each designed to absorb different segments of the solar spectrum, to enhance energy conversion efficiency. By stacking these layers, each optimized for specific wavelengths of light, these cells can capture a broader range of solar energy compared to traditional single-junction cells. This increased efficiency makes multi-junction solar cells particularly valuable for applications where space is limited, such as in satellite technology and concentrated solar power systems.
