Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector
What We have Learnt from PM6:Y6
Over the past three years, remarkable advancements in organic solar cells (OSCs) have emerged, propelled by the introduction of Y6—an innovative A?DA'D?A type small molecule non?fullerene acceptor (NFA). This review provides a critical discussion of the current knowledge about the structural and physical properties of the PM6:Y6 material combination in relation to its photovoltaic performance. We address the design principles behind PM6 and Y6, the mechanisms for charge transfer, transport and recombination, before turning to a detailed examination of the blend morphology and mechanisms of degradation, to conclude with considerations of commercialization. We focus on presenting the current state of the art, while we also discuss unresolved contentious issues, such as the blend energetics, the pathways of free charge generation, and the role of triple states in recombination. As such, this review aims to provide a comprehensive understanding of the PM6:Y6 material combination and its potential for further development in the field of organic solar cells. By addressing both the successes and challenges associated with this system, we hope to contribute to the ongoing research efforts towards achieving more efficient and stable organic solar cells.This article is protected by copyright.
