Abstract
Lead halide perovskites are a novel optoelectronic material which has received enormous attention, with over 6500 scientific articles on SciFinder since 2015. Lead halide perovskites have impressive optical and electrical properties, making fantastic LED’s and Solar Cells. This project shows that spin coating, a commercially common as well as inexpensive process may be used to epitaxially deposit thin films of cesium lead bromide onto many diverse substrates. The Switzer Group has made single crystal gold foils, a promising substrate. Additionally, the Switzer group has shown that CsPbBr3 is epitaxial on epitaxial gold on silicon wafers. These two findings together lead to the prospect of epitaxially depositing Cesium Lead Bromide onto flexible gold foils. This leads to many applications in flexible LED’s, flexible highly efficient solar panels, and wearable technology.
Biography
John Tubbesing is two years into his B.S. in Chemistry and hopes to graduate in December 2019 and then pursue graduate studies. He has been working in Dr. Switzer’s lab since May 2017 and is helping to submit two papers in the very near future. His projects have included research with chiral surfaces and electrochemistry.
