Prof. Gang Pei is a Professor of University of Science and Technology of China and the dean of Department of Thermal Science and Energy Engineering. He received his doctorate in engineering thermal physics in 2006 from the University of Science and Technology of China. He has been engaged in the fields of solar energy utilization for a long time. His main achievements are as follows:

1. A study on a novel solar photovoltaic/thermal (PV/T) system. The PV/T system, which exploits photovoltaic/thermal conversion, has significantly increased the photovoltaic/thermal efficiency and utilize the solar energy in whole wavebands.

2. A study on the photovoltaic-solar heat pump system. The heat pump performance and solar energy utilization efficiency were significantly improved through dynamic integration of the multifunction heat pump cycle with photovoltaic/thermal conversion.

3. By combining the physical properties of scattered and low density solar energy with excellent low-temperature thermal properties of the organic Rankine cycle, the distributed solar energy combined a cooling-heating-power system based on the organic Rankine cycle was proposed. Several critical problems involving the thermodynamic cycle were further studied.

4. A combined solar heating and radiative cooling system. The system can gain heat energy during the day via photo thermal conversion and cooling energy at night by radiating heat into outer space through the atmospheric window.

He has published more than 140 papers in journal and conference proceedings, and obtained 23 national patents in the research fields. He has also been awarded a Marie Curie Visiting Scholarship Award from the EU, the Lu Jiaxi Young Talents Award from CAS, the New Century Excellent Talents Award from the Ministry of Education, and the Excellent Youth Fund Award from Anhui Province, as well as runners-up for the CAS Outstanding Teaching Achievements Award.
