Our current research focuses on high performance, low cost electronic materials and devices including Perovskite Solar Cells, Photodetectors, and X-ray Imagers. Our interdisciplinary research team hosts scientists with different backgrounds of chemistry, materials, physics, and electrical engineering. We focus on applied research, while we are strongly interested in fundamental understanding of science that enables the applications.
We have a strong collaboration culture, and nearly all of our projects have collaborators from academia, industry and national labs. We train the next generation of scientists and engineers to help them succeed in a very competitive job market as well as in future careers, either in academia or private sectors.
Our Current Research Interest
Perovskite Solar Cells
Perovskite materials are arising as a new generation of solution processable metal halide perovskite photovoltaic materials.Our research on perovskite solar cell involves in:
-
Understanding the fundamental material and devices physics, mainly the photon to charge carrier conversion, to explore the theoretically attainable highest efficiency;
-
Device design, material processing and material chemistry for the record power conversion efficiency of perovskite solar cells;
-
Understanding the physical and chemical properties of perovskites to enhance the stability of perovskites devices;
-
Scalable manufacturing of perovskite solar panels;
X-ray detection
We are interested in developing perovskite materials based X-ray detectors for X-ray imaging and γ-ray radiation detectors for spectroscopy, which is based on our discovery of ultra-long carrier diffusion length in the strong radiation-stopping perovskites .
We are developing perovskite pixel detectors and array detectors for X-ray imaging. The next generation of X-ray detectors will be much more sensitive, clearer due to the improved resolution, and cheaper.
The perovskite gamma-ray single-photon detectors can potentially give high resolution gamma-ray spectroscopy, but are 100-1000 times cheaper than the state-of-the-art products.
Highlight of Recent Publications
Shangshang Chen, Xuezeng Dai, Shuang Xu, Haoyang Jiao, Liang Zhao, Jinsong Huang*, Science, 20 Aug 2021, Vol. 373, Issue 6557, pp. 902-907 DOI: 10.1126/science.abi6323
The buried interfaces of perovskite solar cells are difficult to alter after synthesis. During manufacture, Chen et al. removed perovskite films with dimethyl sulfoxide solvent from the hole-transfer layer and observed a substantial void fraction that degraded film performance. Replacing most of the dimethyl sulfoxide with carbohydrazide, a lead-coordinating compound with a much higher boiling point, eliminated voids. Such solar cells maintained high power conversion efficiency after 550 hours of operation at 60°C. —PDS
