NSRRC User Chien-Lung Wang Contributed Critically to a Collaborative Research on Novel Perovskite Solar Cells Published in Science
NSRRC User Prof. Chien-Lung Wang (Department of Applied Chemistry, National Yang Ming Chiao Tung University) participated in an international collaborative research and made critical contributions to the groundbreaking research on perovskite solar cells (PSC), which passed standard industrial lifetime assessment tests and made it possible to be commercialized. The research results were published in the world’s top journal Science.
In the development of novel PSCs, one of the persistent obstacles has been successfully passing the damp-heat test. The team fabricated damp heat-stable PSCs, which delivered a 24.3% power conversion efficiency and retained >95% of their initial value after >1,000 hours at damp-heat test conditions, thereby meeting one of the critical industrial stability standards. Prof. Wang used the grazing-incidence wide-angle X-ray scattering (GIWAX) at TLS 17A1 to analyze the structure of the tailored dimensional fragments of 2D perovskite layers, providing evidence to the novel 2D/3D perovskite heterojunction. This research was regarded as a significant step toward the next-generation commercialized PSCs.
