[Seminar] Interface Engineering towards High Efficiency Perovskite Solar Cells -Dr. Zonghao Liu

Abstract: Organic–inorganic halide perovskite has received extensive attention as a light absorber for low-cost and high-performance photovoltaics. Its superior optoelectronic properties are attractive among most thin film absorber materials, such as high absorption coefficient, tunable band gap, ambipolar carrier transport property, and high defects tolerance. However, it requires suitable electrodes and charge transport materials to fulfill efficient photovoltaic process within an entire device. Thus, interface engineering at counter electrode interface, electron or hole transport materials/perovskite interface is a useful strategy to achieve high efficiency perovskite solar cells. In this talk, the reporter will introduce their work about interface engineering towards high efficiency planar perovskite solar cells and fully printable carbon electrode based mesoscopic perovskite solar cells. 

Short bio: Zonghao Liu received his B.S. in Applied Chemistry from Huazhong University of Science and Technology, China in 2011 and Ph.D. in Opto-Electronic Information Engineering at Wuhan National Laboratory for Optoelectronics in 2016. He was a research intern in 2015 at University of California, Los Angeles, under the supervision of Prof. Yang Yang. Now, he works in Prof. Huanping Zhou's group as a research assistant in Department of Materials Science & Engineering at Peking University. His current research interest is in electronic devices based on inorganic/organic perovskites, especially on perovskite solar cells.
