July 8, 2019: Our team's research on biosensors is featured in SPIE news! Some fun snippets from the article:
"Some may see Fatima Toor's diverse research interests as eclectic: photovoltaics, biosensors, lasers, and semiconductor optoelectronics may not seem to have much in common at first blush. But Toor, who is a professor of electrical engineering at the University of Iowa, doesn't see it that way. From her perspective, her work on laser therapy is a close cousin to her research into photovoltaics. "It's pretty synergistic," she says. "Photovoltaics are light detectors. You basically detect light to generate power, whereas lasers, you inject power and get light out. A lot of these things are very interrelated when it comes to devices.""...
""My favorite part of being in academia is that you have so much intellectual freedom," she says. "As long as you're getting funded, you can work on what you want." Lucky for us, she wants nothing less than a better, healthier world."

Modeling the Performance of Photovoltaic Systems using the Open Source PVLIB Toolbox in Matlab and Python
Dr. Joshua Stephenson Stein
Distinguished Member of Technical Staff
Sandia National Laboratories
Thursday February 25th 2016 3:30 PM to 4:20 PM
Room 2229 SC
PVLIB is a set of open source modeling functions that allow users to simulate most aspects of photovoltaic (PV) system performance. The functions, in both Matlab and Python, provide users the ability to track the energy of the Sun as it interacts with a PV system and is eventually transformed into usable electric energy that is fed to the grid. This talk will combine an overview of the mathematical and conceptual models used to describe PV system performance as well as demonstrate how these models can easily be run using the PVLIB suite of high level functions. Come learn how to predict the output of a solar PV system!

January 23rd, 2016: Professor Toor, Wenqi, Ehteshamul, Ella, and Jason ran the Photonics Camp with some amazing female role models, Michelle Evans and Chelle Lehman today! The camp received more enrollment than we had planned indicating there is not shortage of smart little girls in Eastern Iowa! We had 100% attendance! Smile-filled snapshots below:
- P9.00003 : Towards the design of high performance IR photonics: Optical analysis of textured gallium antimonide surfaces
- B46.00012 : Optical design of a compact near-infrared multispecies gas sensor
See you at the meeting in March!
December 21st, 2015: In a landmark legislation today, lawmakers in the House and Senate passed a spending package that includes multi-year extensions of solar and wind tax credits, plus one-year extensions for a range of other renewable energy technologies. Under the legislation, the 30 percent Investment Tax Credit (ITC) for solar will be extended for another three years. It will then ramp down incrementally through 2021, and remain at 10 percent permanently beginning in 2022. This is great news for the U.S. and for the research that the Toor Lab and Advanced Silicon Group are conducting! Cheers!
December 19th, 2015: Ella graduates with outstanding performance from the University of Iowa with a BSEE degree and a minor in Mathematics! She gets promoted within the Toor Lab from an Undergraduate Researcher during Fall 2015 to a full-time Research Staff Member starting Janauary 2016 through June 2016. So proud of our Ella!

Presentation Title: “Mining PV system data to identify performance trends”

Abstract: The rapid reduction in photovoltaic (PV) system cost has led to an exponential increase in the number of PV systems installed. Questions have been raised about whether this rapid cost reduction has also resulted in a corresponding reduction in quality and performance for these PV systems. We have also seen an increase in the adoption of distributed power electronics (micro inverters, power optimizers) in PV installations. This provides us an unprecedented level of performance monitoring granularity within the PV system. This talk will describe recent analysis of 50,000 PV systems in the US 1603 Treasury program, and will also discuss the impact of distributed electronics on the design and performance of residential PV systems.
Christopher Deline received the B.S., M.S., and Ph.D. degrees from the University of Michigan, Ann Arbor, in 2003, 2005, and 2008, respectively, all in electrical engineering. His Ph.D. work involved experimental investigation of the magnetic nozzle region of electric propulsion thrusters at NASA MSFC and JSC. Since 2008 he has been a research engineer at the National Renewable Energy Laboratory in Golden, CO in the photovoltaic performance and reliability group. He has co-authored several reports on the performance impact of microinverters and DC-DC converters in PV systems under mismatched and shaded conditions. His research includes PV field performance including thin-film PV performance and stabilization, mismatch and partial shading in PV systems and distributed power electronics for PV. Chris manages the DOE Regional Test Center program at NREL for field assessment of novel PV technologies, and is principal investigator for multiple projects on PV field performance including degradation rate assessment and bifacial module power rating and energy production modeling.
