Liquid-assisted crystal growth cuts perovskite defects for efficient solar cells and LEDs‎

A research team led by professor Seong Sik Shin of the SKKU Advanced Institute of Nanotechnology (SAINT) at Sungkyunkwan University (SKKU), in international collaboration with the Korea Research Institute of Chemical Technology (KRICT), the University of California, San Diego, and Princeton University, has developed a next-generation perovskite semiconductor thin film with dramatically reduced defects. Using the same material platform, the researchers demonstrated both high-performance solar cells and LEDs.
