Jeff joined the Hope College faculty in 2018. He primarily teaches chemical engineering courses and has a diverse educational background in chemical engineering and chemistry.

Areas of Expertise

Jeff works on the development of the semiconductor materials which are the working component of solar cells to make solar cells more broadly accessible. These solar cell materials, and even complete solar cells, can be made through the use of simple printing and coating methods, like those used for making photographic film or printing newspaper, from 鈥渋nks鈥� which could allow for dramatically cheaper production. Jeff also works on non-traditional applications of solar cells, such as color-switching solar cells which could be integrated into building facades.
