Project Title

Developing the Electrochromic Layer for Solar-Powered Smart Windows

This summer, I interned with the Loo Group in the Organic and Polymer Electronics Laboratory, where I researched electrochromic device fabrication for use in solar-powered smart windows. Because electrochromic materials have optical properties that can be tuned by the application of small external voltages, these windows would provide tremendous savings in lighting and cooling costs compared to traditional windows. As an intern, I used existing literature and previous experimental data, in addition to independent laboratory experimentation and data analysis, to optimize an electrochromic layer composed of a gel electrolyte and conducting polymer electrodes. This can then be integrated with a photovoltaic layer for a complete device. Through this internship, I was able to develop laboratory skills, collaborate with other researchers, and practice formally presenting my work in an environment that supported independent thinking and hands-on engagement.
