Wajid Ali is a materials physicist and chemist at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, specializing in enhancing the stability and performance of perovskite solar cells and exploring their applications in hybrid energy systems and advanced devices such as resistive random-access memory (RRAM). His research focuses on ferroelastic twin-domains in metal halide perovskites and the integration of perovskite materials into functional energy and memory devices. Wajid has extensive experience in material characterization techniques, including transmission and scanning electron microscopy (TEM, SEM), atomic force microscopy (AFM), grazing-incidence wide-angle X-ray scattering (GIWAXS), X-ray diffraction (XRD), UV-vis and photoluminescence spectroscopy, and impedance analysis, as well as device fabrication skills for solution-processed perovskite solar cells in both conventional and inverted structures. Professionally, he has conducted research on piezoelectric and ferroelectric materials at Nanjing University of Science and Technology and served as an assistant professor teaching physics at the Royal College of Sciences in Pakistan. Wajid’s work has been recognized with awards such as the 2024 Yanchang Petroleum Outstanding Doctoral Student Scholarship, the 2023 Excellent International Students of UCAS, the Academic Innovation Award from FReCAP, the CAS-TWAS fellowship, and the Merit Award at Quaid-i-Azam University. He has contributed to over a dozen peer-reviewed publications in high-impact journals including Nature Communications, ACS Energy Letters, ACS Applied Materials & Interfaces, Materials Chemistry and Physics, and Journal of Alloys and Compounds, advancing the understanding of ferroelasticity, lattice tuning, and suppression of non-radiative recombination in perovskite solar cells. Additionally, he has presented his research at international conferences such as the International Symposium on Solar Fuels and Solar Cells and the Young Scholars Forum on Perovskite Materials and Devices, collaborating with prominent researchers including Prof. Can Li, Prof. Xin Guo, and Prof. G.H. Jaffari.
