CHIEH-TING LIN'S LAB
Research Field
Dr Chieh-Ting Lin received his BSc from National Cheng Kung University in Taiwan, together with exchange programs at Temple University in U.S and Osaka University in Japan. He then continued his MRes and PhD under the supervision of Professor Martyn Mclachlan and Professor James Durrant at Imperial College London in U.K. His project focused on enhancing the stability and efficiency of perovskite solar cells and probing the origin of these enhancements via material and photophysics characterisations. He then worked on the development of stable organic photocathodes as a research associate at Imperial College London. Later on, he moved to Gwangju Institute of Science and Technology and focused on large-scale perovskite and organic solar cells. He is now an assistant professor at National Chung Hsing University, Department of Chemical Engineering, and his research focuses on single crystal perovskite solar cells and all perovskite tandem solar cell.
Our lab focuses on advancing perovskite solar cell technology through innovative research. We aim to improve their efficiency and stability by exploring surface modification, defect passivation, additive engineering, and tuning the composition of perovskite to approach the ideal band gap. We are also interested in developing wide-bandgap perovskite solar cells, which offer improved efficiency due to their lower absorption threshold, and Sn-Pb perovskite solar cells, which offer better stability and lower toxicity than Cs-based perovskites. We are exploring approaches such as materials engineering and device optimization to enhance the performance of these solar cells. Our goal is to contribute to the development of sustainable and efficient solar cell technologies that can mitigate climate change and provide clean energy for the future.
