From 7:00 pm to 9:00 pm of November 13, the lecture “Chalcogenide thin film solar cells: state of the art and perspectives”, which was presented by Professor Deniel Lincot, Director of Research at CNRS and Director of the Institute for Research and Development of Photovoltaic Energy, was held successfully in the lecture theater 217 of the West Building No. 5.

This lecture was again hosted in English all through by the student Wang Kai of our institute. With previous experience as host and by harder study at other times, compared with last-time hosting, Wang Kai has made an obvious improvement in hosting level this time. Not only did he speak more fluent English with more native pronunciation but also show more flexible facial expression and body language. Based on the objective of comprehensively cultivating students’ multi-aspect abilities, our institute will implement the policy of allowing students to host in English all through, as always.
