According to the official website, Xue Jingjing is currently mainly engaged in the research of silicon-based metal halide perovskite optoelectronic materials and devices, and is committed to revealing the relationship between the surface interface physical and chemical properties of perovskite materials, the crystal structure , the crystal growth mechanism and the behavior and stability of device carrier , so as to develop efficient and stable perovskite optoelectronic device .
has published more than 30 SCI papers, including the first or corresponding author in journals such as Science (2 articles), Nat. Rev. Mater., Nat. Photonics, Adv. Mater., Joule, J. Am. Chem. Soc. Many papers have been selected as ESI hot topics and highly cited papers, and their results have been widely reported by many internationally renowned media including Scientific Americans and Forbes. He has served as a reviewer of internationally renowned journals such as J. Am. Chem. Soc., Nano Lett., ACS Nano, ACS Energy Lett.

In 2019, Xue Jingjing published an article on Science as a joint work "Constructive molecular configurations for surface-defect passivation of perovskite photovoltaics". It found that theophylline can effectively improve the efficiency of perovskite to 23%. In addition, the battery maintains 90% original efficiency after working continuously for 500 hours.
021, Xue Jingjing once again published an article in Science as a joint work "Reconfiguring the band-edge states of photovoltaic perovskites by conjugated organic cations". They introduced organic conjugated cations to reconstruct the band edges and designed a pyrene-containing organic ammonium, which once again improved the efficiency and stability of perovskite batteries.
In response to the key issues in the field of perovskite photovoltaic , Xue Jingjing once said in an interview with Advanced ScienceNews: The photoelectric conversion efficiency of
perovskite solar cell has exceeded the 25% mark in just over a decade, which can be regarded as a "miracle" in the field of photovoltaics, and its solution film preparation method has also shown industrial advantages.However, nature is fair, and the easy formation of perovskite materials also means that they are easily destroyed, so the biggest bottleneck of perovskite solar cell technology at present is its stability issue. The development of packaging technology may basically solve the external stability problem, but the intrinsic stability of perovskites is still a difficult problem that needs to be overcome. Through the past years of research accumulation, we have known that water, oxygen, light, heat, electricity, etc. will all induce or promote the degradation of perovskites. At this stage of the development of perovskite research, we may need to shift our attention from its "why degradation" to "how degradation", conduct in-depth research on its microdegradation mechanism, comprehensively grasp its degradation path, and thus develop a targeted stable strategy.
The specific scientific question she is more interested in is to jump out of the perovskite based on perovskites. Through research on this material, she constantly asks herself: Why can this material have such good photovoltaic characteristics? What's special about it? How do we learn from the success of perovskites to discover the next "perovskite"?
Teachers from Daniu
This immortal research group trained more than 40 young professors
After graduating from undergraduate studies, Xue Jingjing studied for her doctorate degree from the School of Materials Science and Engineering at the University of California, Los Angeles, and studied under Professor Yang Yang (Yang Yang), an internationally renowned scholar in the field of semiconductor optoelectronic materials and devices.
Professor Yang Yang is a professor of Carol and Lawrence E. Tannas Jr. from the School of Materials Science and Engineering of the University of California, Los Angeles (UCLA). He was selected as a member of the American Association for the Advancement of Science and Technology, American Society of Physics, American Society of Materials Research, Royal Society of Chemistry, American College of Electromagnetics and International Society of Optoelectronics.
Professor Yang Yang
Professor Yang Yang's research group has more than 20 years of research experience in Semiconductor materials and devices, and has created many world records in this field. The main research directions are solar energy and high-efficiency electronic device , and have made outstanding contributions in the fields of solution processing graphene, organic photovoltaics, quantum dot , CIGS and perovskite solar cells.
The research team trained about 55 postdoctoral fellows, of which about 40 became teachers in colleges and universities, spread all over the world. The research team has published more than 300 papers in famous academic journals, and the published papers have been cited more than 100,000 times.
Professor Yang Yang himself accepted the invitation of Shi Yigong in 2018. He joined Hihu University as the dean of the School of Engineering. Later, for various reasons, he resigned from the position of dean of the School of Engineering and chair professor of the West Lake University School of Engineering in October 2020 and returned to Hihu University .
Once a media asked Professor Yang Yang’s scientific research team how high quality and high productivity?
Professor Yang Yang said: "Walking out of the comfort zone, people must have dreams. One of the secrets of high productivity is to establish a research group culture."
Professor Yang Yang said that his team has several characteristics:
First, students who have been trained by us have very strong independence. I require students to be able to come up with new ideas on their own, publish articles in first-class journals, and even write simple research plans, apply for funds from government agencies, and be able to make good self-statements.
At the same time, I also require students to be teaching assistants, because being teaching assistants is the best way to train people to communicate. Especially when you come to colleges and universities to teach or start your own business, you need to have the ability to convince others.
Another feature is that it allows students to lead the research direction. There are twenty or thirty people in a research group, from different fields, and just communication between students can generate some cross-field ideas. I also send students to academic conferences to learn about new research directions, and they often come up with more new ideas.
Professor Yang Yang also mentioned Xue Jingjing's scientific research in an interview:
Let me give you an example, which is about Xue Jingjing's scientific research. Jingjing is a top student in the Department of Chemistry, , Nanjing University. Before she joined my research group, she was good at synthesising inorganic quantum dots. After she joined my research group, she naturally continued to synthesize perovskite quantum points.
She believes that the high surface area of quantum dots has the opportunity to change the stability of perovskites. This theory is correct, and I know she is very interested in this direction, so I didn't stop her either. Until two years later, she came to tell me that the work of quantum dots could not continue to go further because efficiency could not be improved.
So I started to discuss with her the general direction of her doctoral thesis, because she has two years of experience, which can help them make better decisions. The focus of this consideration is not only whether one direction can be made, but more about whether it can be combined with her interests and the strengths of our group.
Finally, she chose to do perovskite interface research. This direction is actually her perspective on quantum dots: to modify the surface in quantum dots and apply it to perovskite films and crystals. Afterwards, she and Wang Rui published the famous article on caffeine passivation perovskite, which received widespread attention and reports. Later, when I arrived at West Lake University, they conducted further systematic research on this research work from the molecular structure, and finally published this work in Science magazine.
Xue Jingjing also said in her later memories: "Teacher Yang always encourages us to contact different fields and keep our thinking fresh. When I first joined the research group, it was really difficult for me to choose a highly free project, but looking back, it is precisely because of this experience that I have the opportunity to broadly explore different fields and think independently. Whether it is success or hit a wall, this process allows me to wash my own gold. Because of this, after graduation, I am willing to step out of my comfort zone and explore completely different biomedical fields. "
encourages students to use part of their own time to lead the research direction in their own interests and majors. This research group model builds trust to the greatest extent, cultivates students' sense of research responsibility, and also makes students more motivated, more independent and more creative.
Professor Yang Yang also said: Our research team emphasizes teamwork very much, so we have people from different fields, backgrounds and expertise, working together, completing a lot of work more efficiently and achieving common goals.
