Organic photovoltaic (OPV) cells have attracted broad research attention, because organic semiconductors offer advantages, including mechanical flexibility, light weight, and facile module manufacture by high-throughput printing methodologies, vis-a-vis conventional inorganic solar materials. In this study, we report the realization of new, readily accessible donor polymers and their implementation in high-efficiency solar cells and modules. These polymers yield OPV cells with certified PCEs of >14% and values of 12%–14% when the photoactive blend is processed in ambient and/or without halogenated solvents. Finally, we demonstrate the fabrication of a large active-area module (>20 cm2) with certified PCE of 10.1% (22% indoor lighting), which is by far the highest PCE reported to date. This work represents an important step forward in the development of OPV materials for fabricating large-scale OPV modules with extremely high figures of merit, inferring that OPV cells can reach commercialization.
