Plasmon-Exciton Coupling for Enhanced Organic Photovoltaic Systems
Abstract: Currently, over 80% of energy is derived from fossil fuels, and with the global energy demand expected to double by 2050, new carbon-neutral energy resources must be developed to stabilize atmospheric CO2 in hopes of curbing climate change. Recently, organic photovoltaics (OPV) have been intensely investigated, as such systems have potentially low manufacturing costs and could become cost competitive with fossil fuels if their power conversion efficiency could be increased to near their theoretical maximums. In this talk, we present studies designed to better understand the fundamental energy and electron transport processes in bio- inspired organic/inorganic hybrid nanostructures, which have shown great promise for OPV devices. We look to enhance this transport through the coupling of excitons of supramolecular dye aggregates and plasmonic surface lattice resonances (SLRs) of gold nanoparticle arrays. Experimental data will be presented showing strong coupling between the two systems, as well as preliminary data showing enhanced exciton diffusion lengths, due to these coupling mechanisms.
Biography: Professor Trevino currently serves as the NanoFabrication Facility Director at the City University of New York (CUNY) Advanced Science Research Center (ASRC). In this role, he works closely with CUNY faculty researchers as well as external researchers to fully develop the ASRC cleanroom’s state-of-the-art core facilities. Prof. Trevino is also a Research Associate Professor at the CUNY ASRC and faculty in the Chemistry and Physics PhD Programs at the CUNY Graduate Center, leading several collaborative research projects with academic and industry partners across the greater New York City region. His current research topics span the fields of nanophotonics, bio-nanotechnology, micro-electromechanical systems (MEMS) and novel nanofabrication techniques. Prof. Trevino is also Adjunct Associate Professor at Columbia University in the Department of Electrical Engineering. He holds a BS in Physics and Mathematics from Susquehanna University (2002), a MS in Electrical Engineering from Case Western Reserve University (2005) and a PhD in Materials Science and Engineering from Boston University (2013).
