Previously reported glass-forming perylenediimide (PDI-glass) and diketopyrrolopyrrole (DPP-glass) acceptors were used as ternary components to modulate the morphology and electron transport properties of bulk heterojunctions composed of the polymer blend poly(3-hexythiophene) (P3HT) and [6,6]-phenyl-C₆₁-butyric acid methyl ester (PC₆₁BM). Both ternary acceptors show strong absorption in the visible range and energy levels intermediate between that of P3HT and PCBM. In the blends, both amorphous materials occupy the interface between P3HT and PCBM domains without significantly altering film morphology. The incorporation of 20% PDI-glass and 15% DPP-glass in ternary blend devices has resulted in conversion efficiency enhancements of 38% and 36%, respectively. Additionally, the incident photon to electron conversion efficiency of the ternary devices of these materials was increased with additional photocurrent between 660 and 750 nm, indicating that these materials efficiently contribute to light harvesting. This justifies the efficiency enhancements via the charge transfer mechanism. Furthermore, these ternary devices show high stability towards both moisture and oxygen.

先前报道的形成玻璃的per二酰亚胺（PDI-玻璃）和二酮吡咯并吡咯（DPP-玻璃）受体用作三元组分，以调节由聚合物共混物聚（3-己噻吩）（P3HT）和[6,6]-苯基-C _61-丁酸甲酯（PC ₆₁BM）。两个三元受体在可见光范围内均具有较强的吸收能力，且能级介于P3HT和PCBM的能级之间。在共混物中，两种无定形物质都占据了P3HT和PCBM域之间的界面，而没有显着改变膜的形态。在三元共混装置中加入20％PDI玻璃和15％DPP玻璃可分别将转换效率提高38％和36％。此外，这些材料的三元器件的入射光子至电子的转换效率随着660至750 nm之间的附加光电流而增加，表明这些材料有效地促进了光的收集。这证明通过电荷转移机制提高效率是合理的。此外，这些三元器件对水分和氧气均显示出高稳定性。
