# Photo-transformable stabilizer boosts perovskite-organic tandem solar cell performance

Researchers developed a photo-transformable stabilizer that enhances the durability and efficiency of perovskite-organic tandem solar cells. The stabilizer dynamically protects the material from degradation under light, addressing a key barrier to commercialization. This advance could accelerate the adoption of low-cost, high-efficiency solar technology for renewable energy.
