Undergraduate physics majors Chris Lum and Elijah Allen presented posters of their thesis work in the Collins lab at the WSU Physics and Astronomy Fall 2023 Symposium.

Chris’ thesis is titled “Charge mobility of organic semiconductors.” Chris measured the hole mobility in the OLED polymer F8BT using the space charge limited current technique on devices he fabricated.

Elijah’s thesis is titled “Comparing solvent processes for organic solar cells.” Elijah measured radiative and non-radiative voltage losses in solar cells printed via different solvents using absorption spectroscopy and quantum efficiency techniques.

Congratulations to Chris and Elijah!
