Scientists just shattered a solar record. Perovskites beat silicon at its own game. A new efficiency breakthrough hit 28%. That's higher than any standard silicon panel. How? They stacked the materials. Two layers capture more sunlight. Silicon panels top out around 22%. Perovskites were fragile. Not anymore. This changes everything. Cheaper energy. Flexible panels. Even windows that generate power. The lab results are real. Commercial production starts next year. Solar power just got a serious upgrade.
