The McGehee group is currently doing research on perovskite solar cells as well as dynamic windows that have adjustable tinting. This research builds on our prior investigations of organic light-emitting diodes and lasers, light extraction from LEDs, light trapping in solar cells, charge transport in organic semiconductors, nanopatterning, organic and dye-sensitized solar cells and semi-transparent electrodes based on meshes of carbon nanotubes or silver nanowires. The group is inspired to develop technology that can provide humanity with clean energy and solve environmental problems. Although all of our projects have a clear application and we interact closely with companies, we take a fundamental scientific approach that involves sophisticated characterization and advanced modeling.

CHEN 4440 - Chemical Engineering Materials
Primary Instructor
-
Spring 2019
Introduces materials engineering, including properties of polymers, metals, ceramics, and semiconductors, especially as related to chemical engineering processes.
CHEN 4480 - Solar Cells and Optical Devices for Sustainable Buildings
Primary Instructor
-
Fall 2023
This course assumes no background in electronic materials and explains how silicon and cutting-edge metal halide perovskite solar cells are designed, fabricated and characterized. Topics will include optics, band diagrams, wafer fabrication, most thin film deposition techniques, module design and economics. Other optical devices that can help the world rapidly reduce its carbon emissions, such as light-emitting diodes and energy saving windows with dynamic tinting, will also be covered. Recommended prerequisite: a course in materials science (for example CHEN 4440), the physics of electromagnetism and optics at a very basic level. Same as CHEN 5480.
CHEN 4838 - Special Topics in Chemical Engineering
Primary Instructor
-
Spring 2020 / Spring 2021 / Spring 2022
Examines a special topic in Chemical Engineering. May be repeated up to 6 total credit hours.
