Why is perovskite so attractive?
The tandem combines two conversion layers to more efficiently exploit the solar spectrum. This is what makes it possible to achieve laboratory yield records beyond cells conventional silicon.
The real issue: industrialization
Between a laboratory cell and a module guaranteed for 25 years on the roof, the gap is significant: encapsulation, reliability, production rate and cost must be validated on a large scale.
Decision for an owner in 2026
If your goal is to quickly reduce the electric bill, current technologies already offer an excellent level of performance and investment security. Waiting is not relevant only in very specific cases where the project is not urgent.
European perspective
The tandem can strengthen European industrial competitiveness in the medium term. But for one residential project, the priority today remains the quality of design, installation and overall economic dimensioning.
