How are Multi Junction Solar Cells Applied in Real-World Scenarios?
MJSCs are predominantly used in space applications where high efficiency and power-to-weight ratio are critical. They are also being explored for terrestrial applications, particularly in [concentrated photovoltaic](https://) (CPV) systems, where sunlight is concentrated onto a small area of high-efficiency MJSCs using lenses or mirrors. This approach minimizes the amount of expensive semiconductor material required, potentially reducing costs.
