Charge separation and charge transport have been limiting factors in photovoltaic cells that utilize conjugated polymer blends. These authors have exploited the ability of a soluble perylene dye (see Figure) to form crystals within a polymer matrix to achieve a blend that enables good charge transfer and separation, due largely to the crystals' ability to act as electron traps.
