2022年7月29日上午，应特种功能材料重点实验室邀请，新南威尔士大学李建军研究员莅临实验室进行学术交流，本次报告会由特种功能材料重点实验室省特聘教授武四新主持，特种功能材料重点实验室相关领域的老师和学生参加了此次报告会。

李建军老师为大家进行了题为“多晶薄膜太阳能电池中的主要微观载流子损失机制”的报告。李老师首先以效率高于12%的铜锌锡硒（CZTSe）薄膜太阳电池为例，从前后界面载流子传输与复合、带隙与电势波动、自由载流子浓度、载流子收集及晶界与晶粒内复合等方面进行分析，并结合三维器件仿真揭示了CZTSe薄膜太阳能电池中的主导复合机制，对其近年来的工作以及取得的成果进行了详细的介绍。

报告结束后，李老师和实验室师生进行了进一步的交流，现场气氛活跃，李老师的解答更让大家受益匪浅。
