This week at the Energy Symposium, Tim Siegler, postdoctoral researcher in the lab of Brian A Korgel in the McKetta Department of Chemical Engineering at UT-Austin, will present a talk titled "The 10th Birthday of the Perovskite Solar Cell: Will They Ever Grow Up?".
Speaker bio: Tim Siegler is a postdoctoral researcher in the lab of Dr. Brian A Korgel in the McKetta Department of Chemical Engineering at UT-Austin. His research interests include hybrid organic-inorganic perovskites (HOIPs) for tandem photovoltaics and HOIP nanomaterials synthesis. In his time at the University of Texas at Austin, he has authored eight publications on the humidity stability of HOIPs and HOIP-inspired materials and on the development of HOIP-CdTe tandems. Before his current position, he worked in quantum dot PV materials development with Dr. Prashant Kamat at the University of Notre Dame and Dr. Thomas Bein at the University of Munich.
Abstract: Hybrid organic-inorganic perovskites have recently emerged as an extremely promising class of next-generation semiconductors for a wide range of optoelectronic applications, from photovoltiacs and light-emitting diodes to radiation scintillators and photocatalytic absorbers. In particular, perovskites have found tremendous success as absorbers in solar photovoltaics, achieving over 25% power conversion efficiency after only a decade of research. However, their meteoric rise has been dampened by some uncommon technical issues, such as extremely rapid environmental degradation and unique scale-up challenges. In this presentation, we will explore perovskites from the beginning into today, exploring the "how" and "why" behind the invention of the perovskite photovoltiac cell, speaking in detail about the challenges that continue to stall commercialization efforts, and finishing with an outlook for the future of this technology.
The UT Energy Symposium will meet every Thursday during the fall 2019 semester, and is free and open to the public. No RSVP required.
