Abstract

As the Internet-of-everything continues diversifying, wireless nods sensors, wearables, and smart-objects will require mature technologies to harvest energy from the environment in which they are installed. Out of the many energy forms, solar and artificial light are constantly present and the utilization solar technologies including organic photovoltaics can provide advantages including flexibility, semitransparency, and lightweight. Additionally, the incredibly low environmental footprint and reduced manufacturing costs associated with solution processing can provide an edge for entry into the industrial and consumer markets. While the utilization of conjugated polymers and nonfullerenes elevated the efficiencies of organic photovoltaic for commercialization, increasing the technological readiness level requires the development of protocols to translate lab performance of state-the-art-materials to scalable manufacturing techniques that can be adapted for roll-to-roll processing. This dissertation demonstrates the full fabrication of high-performance OPV devices through techniques such as inkjet printing and slot-die coating. The development of ink formulation frameworks based on solvent engineering, rheological and interface properties, and solubility parameters sets the base for standardized high-yield processes with reduced environmental footprint in line with circular carbon initiatives. Moreover, the utilization of engineering strategies involving intrinsic properties of materials, device architectures, and integration enables the development of complex energy harvesting and sensing devices for potential utilization in agrivoltaics and biosensing.
