Some students pick their colleges based on location. Some choose based on cost, while others decide based on the campus vibe.
Mechanical engineering senior Isaiah Henry chose 黑料网 because of the sheer volume of research opportunities and resources that would be available to him as an undergraduate.
As part of the McNair Scholars Program, he鈥檚 been conducting research since his sophomore year alongside faculty from the math and mechanical engineering departments. He worked with 黑料网 mechanical engineering professor Shubhra Bansal for his 2018 McNair project, which was also supported by an Asian American and Native American Pacific Islander-Serving Institutions grant and Louis Stokes Alliance for Minority Participation funding.
Henry worked on developing a more stable perovskite phase for solar cells using a cesium lead bromide composition. Don鈥檛 know what that means? Here, Henry shares his elevator pitch for laypeople.
I first heard about the McNair while I was an Upward Bound student in high school. I knew as soon as I learned about it that I wanted to be a McNair Scholar. So when I became a sophomore and was eligible, I applied.
I鈥檇 been reading a few papers on photovoltaic research 鈥 that is, using solar cells to generate electric power 鈥 and became very interested. I was enrolled in Dr. Bansal鈥檚 Structure and Properties of Solids course, which piqued my overall interest in material sciences. I approached her about being my faculty mentor, and she brought me into the fold of her Center for Energy Research group.
My work there has focused on developing a more stable light absorption phase for solar cells using a chemical composition of cesium lead bromide. All solar cells use a semiconductor to absorb light and generate electricity. Silicon has typically been used as the semiconductor material in the past, but now a perovskite material is being used more often because it is relatively inexpensive. A perovskite material is, simply, a crystal structure. The perovskite I鈥檓 testing is made of the chemical composition CsPbBr3 (cesium lead bromide), which is just one of many different perovskite compositions researchers are investigating to see which ones lead to solar cells that are more efficient at absorbing light.
The amount of useful energy we are able to get out of solar cells depends on the amount of light the perovskite layer is able to absorb, so the development of the perovskite phase is incredibly important if we鈥檙e going to make solar cells more efficient.
That鈥檚 my elevator pitch, anyway. I鈥檓 still practicing it!
Learning how to navigate a research environment has been the best part of the McNair experience. Having weekly goals and presenting updates helped me gain confidence in making technical presentations and explaining terms like 鈥減erovskite phase鈥 to others. I鈥檓 able to have conversations with a diverse educational pool. Our team is composed of masters students, Ph.D. candidates, and postdocs, all working on a variety of projects.
Being in this environment as an undergraduate, I feel that I鈥檓 better prepared for graduate school and have a clear idea of what it takes to be successful there.
The McNair Program is one of the few programs in the country that consistently produces impactful research projects by undergraduate students. My research efforts as an undergraduate are being taken seriously. The program also provides a great starting point for connecting with professors, even if all you have is an interest in getting research exposure. It鈥檚 very good at using its network of faculty mentors to identify projects that students can be a part of.
The McNair Program is truly special to me. The research experience and graduate school preparation I鈥檝e gained through it is invaluable. And being part of Dr. Bansal鈥檚 research group helps me see where the field is heading.
