Ally Hurd—a physics undergraduate student at Macalester College—has concluded her REU 2022 Summer internship working with Collins group. Her work focused on quantifying lifetimes of photo-generated charges in printable organic solar cells (OSCs). That included fabrication of OSCs, characterization and optimization of their device performance. Her charge lifetime experiment, known as transient photovoltage (TPV) measurement, involved light sources such as LEDs, a solar simulator, and nanosecond pulsed wavelength-tunable laser. At the end of the internship, Ally presented her work at the 2022 Summer Undergraduate Research Symposium at Washington State University.
Best wishes, Ally!
