Given the current keen advocacy of energy conservation and environmental protection, the solar cell industry has become one of the key energy industries supported by the state, and also the focus of international high-tech industry competition.

Professor Wu said that he and his team have been in the perovskite battery field since 2013, and have made important progress in the scientific research and industrial technology exploration of perovskite solar cells. In six years, the conversion efficiency of the cells has increased to 23.7%, surpassing the developmental progress of other types of batteries over decades.

He hoped that the research results will be produced as soon as possible and contribute to the development of civil emergency, military and green urban landscape lighting.Ge Chenyang, associate professor of the Institute of Artificial Intelligence and Robots, School of Telecommunications, Xi'an Jiaotong University, introduces the technology of structured light 3D depth cameras.

Ge Chenyang introduced the working principle, application field and market value of structured light 3D depth camera technology. He said that the team's goal is to provide industry-leading 3D vision solutions to solve environmental perception, human-computer natural interaction, obstacle avoidance, 3D scanning, accurate recognition and other problems, and expand applications to robotics, VR/AR, face payment and other fields.

He said that at present, the technology has generated 10 U.S. invention patent applications (six of which have been authorized) and 40 for Chinese invention patents (13 of which have been authorized), and is solving the problem of dynamic, real-time and accurate acquisition of depth maps.

All along, Xi'an Jiaotong University has adhered to scientific and technological innovation, and has been constantly exploring and tackling key problems, constantly promoting the transformation of scientific and technological achievements, and repeatedly making breakthroughs and progress in the field of scientific and technological innovation.
