A perovskite paved pathway to multi-terawatt scale photovoltaics

Joseph J. Berry
National Renewable Energy Lab. (United States)

This talk will consider the future of metal halide perovskite (MHP) photovoltaic (PV) technologies as photovoltaic deployment reaches the terawatt scale. The requirements for significantly increasing PV deployment beyond current rates and what the implications are for technologies attempting to meet this challenge will be addressed. In particular how issues of CO2 impacts and sustainability inform near and longer-term research development and deployment goals for MHP enabled PV will be discussed. To facilitate this, an overview of current state of the art results for MHP based single junction, and multi-junctions in all-perovskite or hybrid configurations with other PV technologies will be presented. This will also include examination of performance of MHP-PVs along both efficiency and reliability axes for not only cells but also modules placed in context of the success of technologies that are currently widely deployed.

Joseph Berry is a Senior Research Fellow at the National Renewable Energy Laboratory working on halide perovskite solar cells. He has experience across multiple photovoltaic technologies as well as doing work in other energy technologies (e.g., light emitting diodes). His efforts at NREL emphasize relating basic interfacial properties to relevant device level behaviors in traditional and novel semiconductor heterostructures including oxides, organics and most recently hybrid semiconductors. He is also a principal investigator on the NREL lead Department of Energy, Solar Energy Technology Offices “Advanced Perovskite Cells and Modules” program, the director of the US-Manufacturing of Advanced Perovskites (US-MAP) Consortium, a thrust lead in the Center for Hybrid Organic Inorganic Semiconductors for Energy (CHOISE) a DOE Energy Frontier Research Center, a Fellow at the Renewable And Sustainable Energy Institute, a joint energy institute between the University Colorado Boulder and NREL and a member of the Physics department at the University of Colorado Boulder.

6:45 PM - 7:25 PM:
Plasmonics for sustainable technologies and green energy: from advancing materials to machine-learning assisted designs

Alexandra Boltasseva
Purdue Univ. (United States) and The Quantum Science Ctr., Oak Ridge National Lab. (United States)

The recent advent of robust, refractory (having a high melting point and chemical stability at temperatures above 2000°C) photonic materials such as plasmonic ceramics, specifically, transition metal nitrides (TMNs), MXenes and transparent conducting oxides (TCOs) is currently driving the development of durable, compact, chip-compatible devices for sustainable energy, harsh-environment sensing, defense and intelligence, information technology, aerospace, chemical and oil & gas industries. These materials offer high-temperature and chemical stability, great tailorability of their optical properties, strong plasmonic behavior, optical nonlinearities, and high photothermal conversion efficiencies. This lecture will discuss advanced machine-learning-assisted photonic designs, materials optimization, and fabrication approaches for the development of efficient thermophotovoltaic (TPV) systems, lightsail spacecrafts, and high-T sensors utilizing TMN metasurfaces. We also explore the potential of TMNs (titanium nitride, zirconium nitride) and TCOs for switchable photonics, high-harmonic-based XUV generation, refractory metasurfaces for energy conversion, high-power applications, photodynamic therapy and photochemistry/photocatalysis. The development of environmentally-friendly, large-scale fabrication techniques will be discussed, and the emphasis will be put on novel machine-learning-driven design frameworks that leverage the emerging quantum solvers for meta-device optimization and bridge the areas of materials engineering, photonic design, and quantum technologies.

Alexandra Boltasseva is a Ron and Dotty Garvin Tonjes Distinguished Professor of ECE at Purdue University. She received her PhD in electrical engineering at Technical University of Denmark in 2004. Boltasseva is the 2023 recipient of the R.W. Wood Prize (Optica), 2022 Guggenheim Fellow, 2018 Blavatnik Award for Young Scientists Finalist and received the 2013 IEEE Photonics Society Young Investigator Award, 2013 Materials Research Society (MRS) Outstanding Young Investigator Award, the 2011 MIT Technology Review Top Young Innovator (TR35). She is a Fellow of the National Academy of Inventors (NAI), SPIE, MRS, IEEE, and Optica.
