Micro- and Nano-Structured Thin-Films for Photovoltaic and Optoelectronic Applications 

Thin-film materials and structures have been widely used for many areas, such as renewable energy and consumer electronics. In the seminar, two research topics will be presented related to thin-film photovoltaics and transparent conductors. Firstly, I’ll present a non-vacuum process to produce earth-abundant thin-film PV absorber from nano-particle solutions, CuZnSn(S,Se) (CZTSSe). Detailed microstructures and film characterizations along with the PV device modeling will be presented to understand the device performance and possible improvement areas. Secondly, I’ll also show the design, modeling and fabrication of a surface plasmonic enhanced nano-structured transparent conductive film.
