My research is on developing next generation transparent conductors for emerging solar cell technologies. Transparent conductors are materials that simultaneously allow visible light to pass through them while having high electrical conductivity, two materials properties that are typically at odds with each other. They’re pervasive in our everyday lives; they’re in the touch screens in our phones, our flat panel displays and they’re a requirement for many different types of low cost solar cell technologies currently under development. The transparent conductors that I make in my resarch are comprised of a thin mesh-like film of randomly oriented silver nanowires which I deposit by spray deposition onto a transparent substrate such as glass or plastic. I develop new high-throughput (&low cost) fabrication and post-processing methods to improve the mechanical and chemical stability and improve optical and electrical performance of these metal nanowire electrodes. I work to solve the challenges that emerge when integrating my electrodes into various solar cells such as those with organo-metal halide perovskite absorber materials or various organic types.

I am in the Advanced Functional Materials and Devices Group here in the Condensed Matter Physics department which is run by Prof. Moritz Riede.
