Yi Cui - Solar Seminar Series
February 28 @ 3:30 PM - 4:30 PM - Birck 2001
Abstract: Advanced photon management using nanostructures provides exciting opportunities for enhancing solar cell device performance. In this talk, I will present examples of photon management at the nanoscale for amorphous Si, crystalline Si and III-V solar cells while balancing electrical charge carrier collection. Nanocone solar cells are simple structures combing an efficient antireflection and light trapping across a broad band of spectra and over a wide range of incident angles. We demonstrated excellent light absorption enhancement and high power conversion efficiency. In addition, I will present novel metal nanowire networks as transparent conducting electrodes to replace the existing indium in oxides. We show that these metal nanowire networks provide high optical transmittance at very low sheet resistance. The low cost processing makes them attractive for future large area optoelectronic applications.
Brief Bio: Since 2010, Yi Cui has been a tenured associate professor at Stanford University, and a David Filo & Jerry Yang Faculty Scholar. He began his career with a BS in Chemistry from the University of Science and Technology of China in 1998. Four years later, he also completed his Ph.D. at Harvard. Afterwards, he served as a Miller Postdoctoral Fellow at Berkeley, until being hired by the Department of Materials Science and Engineering at Stanford in 2005. He currently investigates nanomaterials for energy storage, photovoltaic, topological insulators, biology and environment.
