Spectroscopic and ultrafast dynamics study of poly (3-hexylthiophene) in organic solar cell doped with graphene oxide
EMSL Project ID
42297
Abstract
Organic photovoltaic (OPV) devices have been studied extensively and promise to be efficient and cheap devices to convert solar energy in comparison with their inorganic counterparts. We request the use the single molecule microscope in EMSL to perform spectroscopic and ultrafast dynamics study of poly (3-hexylthiophene) in an OPV doped with graphene oxide nanosheets. This proposed work ties to the EMSL mission by providing molecular level understanding of the photophysical properties of a conjugate polymer and its interfacial charge separation mechanism in an organic solar cell environment. We will also investigate the spatial inhomogeneities of an organic photovoltaic device by correlating the morphology and the fluorescence lifetime to understand how the charge is separated at P3HT interface. The PI and his students will either travel to PNNL or send samples for the requested measurements. We plan to use the requested facility for 150 hours (2 weeks every 6 months) in the first year.
