Perovskite cells now hold their crystal lattice at 85°C, keeping 98% of their efficiency after 1,200 hours – Rice University just proved thermal stability isn’t a show‑stopper. It’s a practical step toward grid‑scale rooftop adoption, but scaling the encapsulation and supply chain still lags. How do we fast‑track manufacturing without compromising durability? #SolarEnergy #Renewable #EcoTech #GreenTechnology
