Perovskite semiconductor materials are of great value to the next-gen new photoelectric materials and devices, and their applications in the energy field. Jingjing Xue devotes herself to the study of metal-halide perovskite photoelectric materials, focusing on the key problems in such materials and devices at the microscopic scale.

She discovered the electronic contribution from A-site ions to the band structure of perovskite and upended the traditional understanding of the structure of electrons in this material. She revealed the surface state and passivation mechanism of perovskite, which provided a theoretical basis for specific passivation molecular design. She also developed new methods to promote the stability of perovskite photoelectronic devices, thus laying the foundation for the industrialization of such devices.

After joining the School of Materials Science and Engineering, at Zhejiang University in 2021, Xue established a research team for perovskite photovoltaic devices with continuous attention to the development of efficient and stable perovskite solar cells, mainly focusing on structurally stable perovskite components and silicon/perovskite stacked cell devices. Her group has developed a new strategy for growing high-quality perovskite films on suede silicon substrates, which is promising to further facilitate the industrialization of silicon/perovskite solar cells.
