(Invited) Roll Coated Organic Dye-Based Photovoltaics for Indoor Energy Harvesting Applications

Abstract

Organic photovoltaics (OPV) remain one of the hottest topics in energy science today owing to the potential to convert the energy of light into electricity in an affordable and versatile manner. Researchers around the world continue to develop new materials, optimize devices, and understand operation resulting in ever increasing power conversion efficiencies. As chemists, developing new photoactive organic materials is of interest. A recent goal has been to move away from fullerene base systems. In the pursuit of new materials to replace fullerenes, our research group has gravitated towards using classic dyes. This presentation will cover the design and practical synthesis of some new organic conjugated molecules based upon ‘dye stuffs’, their use as non-fullerene acceptors in both greener solvent processed OPV cells, translation to large area slot-die coating methods, and operation under indoor lighting environments.
