Strategies for advancing the performance of organic photovoltaics — •Thomas Anthopoulos — King Abdullah University of Science and Technology (KAUST), Thuwal 23955-6900, Kingdom of Saudi Arabia

The dramatic advances in the power conversion efficiency (PCE) of organic photovoltaics (OPVs) witnessed in recent years have been primarily driven by the development of new materials and the minimisation of performance losses associated with conventional cell architectures. This talk will discuss our recent OPV work, focusing on practical strategies for boosting cell performance. I will first discuss using low-dimensional charge-extracting interlayers and the numerous advantages of these innovative materials for next-generation OPVs. I will then present recent progress in using molecular dopants to improve the PCE of OPVs and how their combination with innovative interlayers can improve the material utilisation and circularity of the ensuing OPV cells without compromising their performance.
