The rapid development of non-fullerene polymer solar cells (NFPSCs) with strong light absorption, tunable energy levels, excellent stability, and easy accessibility, NFPSCs performing 15–17% power conversion efficiencies (PCEs) have been reached, which feature enormous promise for the commercialization in the future. In spite of these great achievements made by NFPSCs, there still exist several challenges which hinder them from further applying in roll-to-roll production or practical application. On the one hand, most NFPSCs require extra treatments such as pre/post-thermal heating, and/or solvent vapor annealing to access appropriate film morphology and high efficiencies. However, these complex fabrication procedures usually reduce the reproducibility of NFOSCs and cause additional issues incompatible with the roll-to-roll process. In this study, we designed and synthesized the donor copolymer with no pre/post-treatment for module application in high-performance NFPSCs. |
