Abstract
Abstract Non‐fullerene acceptors (NFAs) have recently breathed new life into organic photovoltaic (OPVs), achieving breakthrough photovoltaic conversion efficiencies. Unlike conventional fullerene acceptors, they offer strong levels of tunability and solution‐processibility that allow them to be easily exploited in the roll‐to‐roll (R2R) fabrication process. This has enabled a new renaissance for OPVs in the face of other photovoltaic material candidates for large‐scale, high‐throughput, cost‐effective manufacturing. In this review, the current progress of R2R manufacturing of NFA‐OPVs and the applications enabled by them are summarized. The perspectives on their research, technological, and future prospects for industry scale‐up are also presented.
