In the first part of this webinar, hosted by the Optics for Energy Technical Group, Eugene Katz will explain why the power conversion efficiency (PCE) of an ideal solar cell should increase with light intensity from the point of view of both thermodynamics and semiconductor device physics. Katz will also discuss another important fundamental feature: the logarithmic decrease of the absolute values of the negative temperature coefficient of the cell PCE with increasing light intensity. In other words, the cell could be more tolerant to heating under concentrated sunlight.

In the second half of the webinar, Katz will discuss the requirements, achievements, and challenges for realizing these basic advantages in real concentrator photovoltaics (CPV) efficiently operating at ultra-high solar concentrations (from hundreds to thousands of suns). The final part of the webinar will focus on the CPV applications in space as well as in hybrid solar systems such as CPV/thermosolar (concentrated solar power) and CPV/thermoelectric devices.

About the Presenter: Eugene A. Katz from Ben-Gurion University of the Negev

Eugene A. Katz is a professor at the Ben-Gurion University of the Negev. He received his MSc degree (1982) in Semiconductor Materials Science and Ph. D. (1990) in solid state physics from the National University of Science and Technology “MISIS”, Moscow. His research interests include studies and development of a wide range of novel materials and devices for solar energy conversion (including organic and perovskite-based photovoltaics, concentrator solar cells operated at ultra-high solar concentration (up to 10,000 suns), as well as a history of science. He has published more than 160 peer-reviewed papers on these topics (including those in Nature Energy, Advanced Materials, Energy & Environmental Science, etc). Prof. Katz was awarded the IAAM Medal (by the International Association of Advanced Materials) for outstanding research in the field of New Energy Materials & Technology.
