High Efficiency: CIGS cells have achieved efficiencies over 20%, which is competitive with traditional silicon-based cells. Flexibility: Unlike rigid silicon cells, CIGS can be deposited on flexible substrates, enabling new applications such as wearable electronics and building-integrated photovoltaics (BIPV). Reduced Material Usage: Thin-film technology uses less material compared to traditional silicon wafers, thereby lowering production costs and environmental impact.
