WUHAN, China (June 22, 2018) - Wuhan Optoelectronics Forum No. 143 was successfully held in Auditorium A101 at Wuhan National Laboratory for Optoelectronics (WNLO) in the afternoon of June 22. Prof. Liyuan Han from Shanghai Jiao Tong University delivered an exciting talk entitled High Performance of Perovskite Solar Cells: from Cells to Module. Prof. Wei Chen, from WNLO chaired the forum. Dr. Song Xia, Chair of WNLO committee, awarded Prof. Liyuan Han the forum medal.
Here I will introduce our main achievements in the fabrication of efficient and stable PSCs with working area over one centimetre square. The first recorded efficiency of perovskite solar cells was obtained by using heavily doped inorganic charge extraction layers with high conductivity. New graded heterojunction (GHJ) structure was designed to improve the electron collection and in inverted structure with Formamidinium based perovskites. Combined with additive engineering, an certified efficiency of 19.2% was achieved.
Liyuan Han, Chair Professor of the Recruitment Program of Global Experts of Shanghai Jiao Tong University, China. He is also the chief Scientist of National Institute for Materials Science （NIMS）, Japan. He received the PhD degree (Engineering) in 1988 from Osaka Prefectural University, Japan. He has worked for DIC and Sharp Corporations in Japan for 18 years. In 2008, he was invited to NIMS of Japan as the director of the Next-generation solar cell center. Professor Han has a high level of success in improving solar cell conversion efficiency and module technology innovation. He has published more than 200 co-authored papers in world’s top journals, including Science, Nature, Nature Energy, Nature Communication, Joule etc., as well as more than 150 authorized patents. In the future, his main research direction is to develop large-area, high-efficiency, high-stability perovskite solar cells and promote the development of industrialization.
