Biography:

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.



报告摘要:

钙钛矿电池由于其优异的光电性能及易于制备的特点,在最近的几年得到了快速发展。在这里,我将主要介绍我们在制备面积超过1 cm2的高效稳定钙钛矿电池方面的工作。我们利用重掺杂高电导率无机电荷传输材料,获得了首个钙钛矿电池认证效率。我们利用渐变异质结结构改善了甲咪基钙钛矿材料在反式结构中电子收集效率。此外,我们结合添加剂工程,在大于1 cm2的面积上获得了19.2%的认证效率。

从小面积电池到大面积模块过渡,最难的环节是开发出制备大面积低缺陷钙钛矿薄膜的方法。此前,我们开发了一种软膜法能够制备这样的薄膜并具有较大的晶粒尺寸。基于此方法,我们成功制备51 cm2的高质量薄膜。最近,我们又开发出一种新的无溶剂钙钛矿前驱体。将此种前驱体应用于软膜法中,我们成功制备了6*6 cm2的钙钛矿模块,获得了12.1%的AIST认证效率,这也是世界首个钙钛矿模块的效率记录。此外,我也会将我们关于钙钛矿电池成本分析和稳定性方面的工作向大家介绍一下。


Abstract: 

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.

For further enlargement of the cell to large-area module, the big challenge is to develop new deposition methods suitable for fabricating large-area perovskite films with low defects density. A soft-cover deposition method was proposed to achieve this goal. We recently synthesized a new non-solvent perovskite precursor and modified the soft-cover method. This combination led to the first perovskite module efficiency record. Furthermore, I will also talk the cost analysis and stability issue of PSCs.
