Temporary melting liquid could help build better perovskite solar cells and LEDs

A team co-led by researchers at the University of California San Diego has developed a new way to make perovskite solar cells more efficient and durable. By creating a temporary liquid while the material crystallizes, researchers grew larger, more uniform perovskite crystals with fewer defects.

• Method forms a temporary liquid during perovskite crystallization
• Crystals grew larger, more uniform and with fewer defects
• Work was co-led by researchers at UC San Diego
• Approach applies to solar cells and LEDs
