(Dr. Fengjiu Yang, Helmholtz-Zentrum-Berlin)

Dr. Fengjiu Yang is a postdoctoral researcher of Helmholtz-Zentrum-Berlin (Germany) from Nov. 2019. His current research mainly focuses on “Band Gap Tailored Perovskites with Reduced Losses and Improved Stability: Towards Highly Efficient All-Perovskite Tandem Solar Cells”. He obtained his B.S. and M.S at University of Jiamusi, and Donghua (China) in 2012 and 2015, respectively. His Ph.D has been finished from Kyoto University (Japan) in 2019 with a topic of “Architecture design for highly efficient perovskite solar cells”. He awarded the Japan Society for the Promotion of Science (JSPS, Japan) fellowship for Young Scientist in 2018, and carried out the project of “Highly Efficient Organic-Inorganic Perovskite Photovoltaic-Thermoelectric Hybrid Device Study” as a DC/PD special research fellow from Apr. 2019 to Oct. 2019. Dr. Yang’s research interests include organic-inorganic hybrid perovskite film growth, interfaces engineering, multi-junctions’ architecture design, flexible device fabrication, and excellent metallic materials application, etc.

Title: High efficiency and low-cost fabrication of perovskite solar cells

Date: NOV. 27, 2020 (Friday) 16: 00

Venue: Room 510, MGI

Abtract:

       Hybrid organic/inorganic metal halide perovskite solar cells (PSCs) have emerged widespread attentions and interesting because of the unprecedented progress of power conversion efficiency (PCE), which has been regarded as a most-promising for next-generation photovoltaics. Although the rapid developed PCE has reached over 25%, the stability of PSCs is still far behind the industrial application requirement. The interfaces nature should a critical issue to improve stability and efficiency. Moreover, the single-time utilization of metal electrode with a complex thermal evaporation process also increase the fabrication cost of perovskite-photovoltaics, induce the concerned issues of environmental pollution and resource waste.

       In this seminar, I will mainly focus on the perovskite growth and nanoporous gold metal material recycled application for high efficient PSCs, and potential commercial application.
