Photoelectric Physics, Semiconductor Materials Science, Energy and Power Engineering
Solar cells, as a green and clean energy source, have always attracted significant attention. Compared to traditional rigid solar cells such as crystalline silicon solar cells, flexible thin-film solar cells stand out due to their advanced flexibility, excellent performance, high photoelectric conversion efficiency, and low cost. They are widely used in various fields, including portable solar backpacks, solar canopies, solar cars, and even solar-powered aircraft. Flexible thin-film solar cells include types such as CdTe, gallium arsenide, perovskite, and CIGS. Among these, CIGS (Cu(In1-xGax)Se2) flexible thin-film solar cells offer unique advantages, such as high theoretical conversion efficiency, adjustable bandgap, suitability for flexible devices, excellent performance in low-light conditions, and potential for use in tandem solar cells. The actual maximum conversion efficiency of CIGS solar cells has reached 23.6%, and there is still a lot of potential for improvement.
This project collaborates with senior experts in the field of new energy and semiconductor from national research institutes to guide students in exploring developments and trends in thin-film solar cells, gaining hands-on experience in the fabrication processes of CIGS solar cells, and developing a deep understanding of the photoelectric conversion principles and related technologies behind solar cells.

XLAB让我受益匪浅。我不仅了解了做科研的流程，更是自己在实验室操作了制作、组装和测试了电池。另外，我也了解了现有锂电池的优缺点和改进方案以及研发新电池的社会意义。锂电池和化学紧密相关，所以XLAB的经历不仅可以丰富我申请化学专业的文书，也对我未来的学习很有帮助。—— 武汉枫叶国际学校 李同学

Why Us
History
XLAB has a 20+ year history. It was initiated by Professor Neher of the University of Göttingen in Germany and strongly supported by the German government and the University of Göttingen. XLAB, centered around high-end scientific experiments, is widely favored by over 10,000 students yearly. XLAB has established practice centers worldwide, aiming to expand this unique concept and teaching method to reach more students.
XLAB aims to enable more people to learn and experience the joy of science, encouraging them to explore the mysteries of science and consider how to use science to solve human problems. Therefore, XALB's subjects are generally more complex in physics, biology, or medicine. Instead, they focus more on interdisciplinary, cutting-edge topics such as genetic engineering, medical research, nanobiology, medical chemistry, high-energy physics, and more.
Subject
Experiment
Experiments are the core of the XLAB. Each participant can enter advanced laboratories to conduct safe experiments, analyze data, and write experiment reports. Over six hours of scientific research daily enhances students' scientific knowledge and logical thinking and cultivates concentration and endurance. Students will be able to experience the work content and status firsthand and consider whether to choose a research direction in future education.
The courses in XLAB are unique. They consist of four key modules: Subject Introduction and Program Thinking, Scientific Research Teaching, Laboratory Operations, Experimental Data Analysis, and Research Report Writing. All courses are taught in small groups of 10 to 25 students.
Course
Faculty
Experts are invited to design experiments and teach students since the topics and content of XLAB exceed the curriculum of high schools and are specialized in specific research areas. Relevant scientific research institutions support XLAB China and provide an in-depth academic experience for Chinese students based on its unique teaching methods and experimental requirements.
Two authoritative certificates are available: the XLAB Program Certificate of Participation, which details the experimental content and is signed by instructors. Students will complete an academic report containing experimental results and data analysis to apply for the ASDAN "Science Award" Certificate for 30 credit hours of study officially accredited by UCAS.
Certificate
Research
XALB provides invaluable research scenarios for students who plan or are currently engaged in natural science research-oriented learning, such as EPQ or scientific papers, to implement their research plans and participate in hands-on scientific research. Experimental reports can be considered as part of their research achievements.
