Ozone generation and chemistry from 222 nm germicidal ultraviolet light in a fragrant restroom

May 20, 2024
Author(s)
Michael F. Link, Rileigh Robertson, Andrew Shore, Behrang Hamadani, Christina Cecelski, Dustin Poppendieck
Devices using 222 nm germicidal ultraviolet light (GUV222) have been marketed to reduce virus transmission indoors with low risk of occupant harm from direct UV exposure. GUV222 generates ozone, an indoor air pollutant and oxidant, under constrained

Electrical and Electroluminescence Evaluation of 17 Year Old Monocrystalline Silicon Building Integrated Photovoltaic Modules

December 25, 2023

Andrew Shore, Tali Schlenoff, Bakary Coulibaly, David Navon, Stephanie Moffitt, Brian P. Dougherty, Behrang Hamadani
Longterm reliable operation of photovoltaic modules is necessary to ensure the technology is key to reducing the cost of solar energy. However, degradation mechanisms in the field are not always consistent or predictable. We present a dataset of 72

Mechanical Ventilation in a Residential Building Brings Outdoor NOx Indoors with Limited Implications for VOC Oxidation from NO3 Radicals

October 10, 2023

Michael F. Link, Jienan Li, Jenna Ditto, Han Huynh, Jie Yu, Stephen Zimmerman, Andrew Shore, Katelyn Rediger, Jonathan Abbatt, Lauren Garofalo, Delphine Farmer, Dustin Poppendieck
Energy-efficient residential building standards require the use of mechanical ventilation systems that replace indoor air with air from the outdoors. Transient outdoor pollution events can be transported indoors via the mechanical ventilation system, and

Ozone Generation from a Germicidal Ultraviolet Lamp with Peak Emission at 222 nm

July 21, 2023
Author(s)
Michael F. Link, Andrew Shore, Behrang Hamadani, Dustin Poppendieck
Recent interest in commercial devices containing germicidal ultraviolet lamps with a peak emission wavelength at 222 nm (GUV222) has focused on mitigating virus transmission indoors while posing minimum risk to human tissue. However, 222 nm light can

Nonlinear Response of Silicon Solar Cells
