Perovskite solar cells have often faced durability problems, so longer-lasting versions matter a lot. Longevity is what turns a lab success into a real market contender.
Improved stability means these cells may stay efficient longer under real conditions. That makes commercial rollout more believable.
The controversy is geopolitical. If the chemistry matures but the supply chain concentrates in a few countries, solar gains could still deepen dependence instead of reducing it.
For Western countries trying to diversify energy infrastructure, material control may matter as much as the record efficiency itself.
Can a clean-energy breakthrough still create new strategic dependence?
