Why CIGS solar keeps lagging behind crystalline silicon

In an interview with pv magazine, Empa scientist Mirjana Dimitrievska explains that the CIGS photovoltaic technology, while promising for efficiency and flexible applications, faces persistent challenges in scaling lab-level performance to cost-effective, high-throughput industrial production, limiting its ability to compete with crystalline silicon. She also emphasizes that long-term stability, reliability, and material sustainability, rather than peak efficiency, are crucial for commercial viability, especially in niche markets like building-integrated and lightweight PV. Despite its promise of good conversion efficiencies and relatively low costs, copper indium gallium diselenide (CIGS)...
