Professor Feijiu Wang is an internationally recognized researcher in the fields of photovoltaic materials, perovskite optoelectronics, nanocarbons, and low-dimensional semiconductor devices. He is currently a Professor at the Henan Key Laboratory of Photovoltaic Materials, Henan University, a position he has held since May 2019, and was promoted to full Professor in May 2023. His research integrates materials science, energy science, and nano-optoelectronics with a strong emphasis on device performance, stability, and interfacial engineering. Prof. Wang received his Ph.D. in Energy Science from Kyoto University, Japan, where he developed a strong foundation in photovoltaic physics and nanomaterials. Prior to this, he earned his M.E. from Shanghai Normal University and B.E. from Huaiyin Normal University. Following his doctorate, he conducted postdoctoral research at Nagoya University under the prestigious JST ERATO Itami Molecular Nanocarbon Project, where he deepened his expertise in nanocarbon materials and their integration into advanced electronic and energy devices. His research focuses primarily on perovskite solar cells and light-emitting diodes (LEDs), carbon nanotube– and graphene-based photovoltaics, two-dimensional semiconductors, and interface and defect engineering. He has made seminal contributions to improving the efficiency and long-term stability of perovskite solar cells through innovative interfacial layers, all-carbon charge transport layers, and polymer-assisted engineering strategies. In parallel, his recent work on perovskite LEDs and light-emitting field-effect transistors has achieved state-of-the-art external quantum efficiencies, addressing key challenges such as phase purity, defect passivation, and charge balance.
