Dr. Liyuan Han is thedirector ofphotovoltaic materials unit, National Institute for Materials Science (NIMS). He received a doctor’s degree from the University of Osaka Prefecture in1988. He worked at SHARP Corporation since 1993 - and moved to current position since 2008. Through his career, he has renewed the world recordefficiency of dye-sensitized solar cells (DSCs, cell and module) for several times. Recently, hehad an interest in perovskite solar cells (PSCs) and also achieved world efficiency bymorphology engineering. He is an inventor in more than 100patents and an author in ca 200 scientific publications in the field of next generationsolar cells. His currentresearch interests involve fundamentalresearch in PSCs, DSCs, and organic solar cells.

 

Title: Efficient and Stable Large-area Perovskite Solar Cells

 

Abstract

 

Organic-inorganicmetal halide perovskite solar cells (PSCs) have reached high power conversionefficiency (PCE) of 18~20%. However, all of the high PCEs were achieved by tinycells (working area << 1 cm2) with very short lifetime. In this presentation,I will focus the discussion on two aspects: one is improving thereproducibility of device performance through controlling the morphology anduniformity of photoactive and charge transport layers in the solar cells; theother is increasing the long-term stability of device by developing new chargetransport materials with low hygroscopicity and high carrier mobility. As aresult, we achieved 15% conversion efficiency in perovskite solar cells (> 1cm2) for the first time in the world through the official evaluation by theinternational standard testing center (Calibration, Standards and MeasurementTeam at the Research Center for Photovoltaics, National Institute of AdvancedIndustrial Science and Technology (AIST))
