4:05 PM: Perovskite Solar Cells

Anita Ho-Baillie, The Univ. of Sydney (Australia)

In this talk, I will give a short overview of perovskite solar cells with regards to their opportunities and challenges. Opportunities for performance improvement will be highlighted. Challenges regarding durability will be discussed touching on our work on understanding intrinsic stability of perovskites and meta-stability of perovskite solar cells and strategies for boosting perovskite solar cells’ durability against thermal extremes and humidity. Our perovskite solar cells were the first to exceed the strict requirements of International Electrotechnical Commission standards for thermal cycling damp heat and humidity freeze. Such a major breakthrough represents an important step towards commercial viability.

Anita Ho-Baillie is the John Hooke Chair of Nanoscience at the University of Sydney. She is a Clarivate Highly Cited Researcher in 2019 and 2020. Her research interests including engineering of solar materials and devices integrating them onto different kinds of surfaces generating clean energy for various applications. Her achievements include setting solar cell energy efficiency world records in various categories and reporting of highly durable perovskite solar cells.

4:45 PM: Light Manipulation of Photonic-Structured OLEDs

Franky So, North Carolina State Univ. (United States)

OLEDs are thin-film devices consisting of multilayers of organic thin films sandwiched between a metal and an ITO electrodes. Because of the different refractive indices of the layers in the thin film stack, different optical modes are trapped in the device. In this talk, we will first discuss the physics of these optical modes and describe techniques to characterize them. We will then describe how to use various photonic structures to maximize the light output and manipulate these optical modes to control the polarization as well as directionality to achieve beam shaping.

Franky So received his PhD from the University of Southern California. He is the Walter and Ida Freeman Distinguished Professor of Materials Science and Engineering at North Carolina State University. Prior to his academic career, he held various technology leadership positions at Motorola and OSRAM. He has over 120 issued patents and patent applications and published more than 200 peer-reviewed articles. So is a Distinguished Lecturer of the IEEE Photonics Society, a Fellow of the National Academy of Inventors, and a Fellow of SPIE, IEEE, MRS, SID, and OSA.
