• Summary:
• Inverted perovskite solar cells offer strong potential for scalable, low-cost solar power, but a hidden interface inside the device has limited their performance and durability. Researchers have now introduced crystal-solvate nanoseeds that guide crystal growth and release solvent in a controlled way during heating, improving film...
