AI Insight
Researchers from Sungkyunkwan University and international collaborators have developed a method to significantly reduce defects in perovskite semiconductor thin films through liquid-assisted crystal growth. This improved material platform enabled the team to demonstrate both high-efficiency solar cells and light-emitting diodes (LEDs) using the same perovskite base material. The advancement addresses a key challenge in perovskite technology by improving crystal quality, which is critical for device performance.
Why it matters
This breakthrough could accelerate the commercialization of perovskite-based devices by improving their efficiency and reliability. The dual functionality for both energy harvesting (solar cells) and light emission (LEDs) from a single material platform demonstrates the versatility of the approach and could reduce manufacturing complexity for multiple optoelectronic applications.
Understand the Science
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.
