Strong exciton\u2013vibration coupling critically impedes exciton transport and triggers detrimental non-radiative recombination in thick films, curtailing exciton diffusion length. Herein, we propose a modulated insulator dilution (MID) strategy, employing tailored molecular weight polypropylene (PP), to achieve high-performance OSCs with exceptional thickness tolerance. Driven by a polymer swelling effect during processing, PP incorporation orders acceptor molecular packing, optimizing fibrous nanomorphology and enhancing \u03c0\u2013\u03c0 interactions within PM6:L8-BO systems. This MID approach effectively suppresses exciton\u2013vibration coupling and optimizes excited-state dynamics. By localized-to-delocalized exciton diffusion enhancement, PP incorporation boosts the efficiency of a 500\u00a0nm device to 15.92%, which is one of the highest values among 500\u00a0nm OSCs. Efficiency remains substantial (\u223c12%) even at a challenging 1-\u03bcm thickness. This work underscores molecular weight-modulated insulator dilution as a pivotal strategy for exciton management and performance enhancement, providing a crucial pathway toward the industrialization of organic photovoltaics.<\/jats:p>","DOI":"10.1093\/nsr\/nwaf387","type":"journal-article","created":{"date-parts":[[2025,9,15]],"date-time":"2025-09-15T11:32:37Z","timestamp":1757935957000},"source":"Crossref","is-referenced-by-count":9,"title":["Suppression
