This project will systematically examine how substrate-bourn defects, as well as larger-scale non-planarity of substrates affect the optoelectronic performance of organic semiconductor-based ultra-thin film devices (e.g. OLEDs, PV cells, transistors, etc.) A combination of fabrication techniques will be used to generate precisely curved as well as micro- and nano-structured surfaces, on which organic devices will be created. Full optical and electrical characterization, coupled with device modeling will be used to elucidate the device physics and mechanisms of breakdown. This work is important for understanding the challenges facing scaled-up and cost-effective fabrication of organic-based optoelectronic devices.
