Our current research focus on the design and fabrication of perovskite solar cells, near infrared photodetectors and X-ray detectors.
The final mission of our group is to design and develop new type photoelectronic devices with low cost and superior performance to serve our country and society. Achieving the ‘Holy Grail” requires the synthesis of novel material, deep understanding of the material photoelectronic properties, smart design of device structure, careful optimization of recipe. Therefore, we proactively collaborated with experts from different fields including chemistry, physics and engineering.
