01 // Products and Technology Perspective

The diversification of production and design of CIGS modules offer multiple possibilities for PV power production in the future. CIGS glass-glass products cover the classical application fields of power plants, roof-tops, and building facades. Flexible and light weight CIGS modules currently in production show average aperture area efficiency > 16 %. Achieving high efficiency with such products will open new large scale applications and markets.

In the longer term in combination with suitable wide bandgap absorbers CIGS can be used as bottom cell in tandem devices that enable efficiency values well beyond 30 %. This demonstrates impressively that not only is CIGS a competitive PV technology, but in addition it comprises a potential not yet exploited for further improvements.
