- The power conversion efficiency of a device incorporating a crystalline polymer/fullerene thin film improves from 5% to 7.3% – a relative increase of 45% – when an additive, diiodohexane (DIH), is present during processing. The DIH‐processed active layer exhibits substantially enhanced polymer crystallinity and smaller fractal‐like fullerene clusters.
