TNO has unveiled what it claims is the world’s first electrically functioning solar roof tile based on flexible perovskite cells. Developed with startup ASAT, the curved composite tile carries a perovskite module on foil and achieves 12.4 percent efficiency after installation. Individual modules reached up to 13.8 percent before bending, indicating limited performance loss from curvature.
The project is part of a broader Brabant-centered push to strengthen Europe’s solar manufacturing base. TNO recently launched Perovion, a company to start mass manufacturing perovskite ‘bare’ foils by the end of the decade. Other firms will turn these foils into end-products. Key hurdles to commercialization include lifetime and reliability.
