Restoring quantum dot solar cells as if 'flattening crumpled paper'

Professor Jongmin Choi’s team from the Department of Energy Science and Engineering at DGIST conducted joint research with Materials Engineering and Convergence Technology Professor Tae Kyung Lee from Gyeongsang National University and Applied Chemistry Professor Younghoon Kim from Kookmin University. The researchers developed a new method to improve both the performance and the stability of solar cells using “perovskite quantum dots.” They developed longer-lasting solar cells by addressing the issue of distortions on the surface of quantum dots, which deteriorate the performance of solar cells.
