In this study, we consider the choice of a standard electron-donating material to be paired with boron subphthalocyanines (BsubPcs) to rapidly assess the viability of new BsubPc derivatives as electron-accepting materials within organic photovoltaic devices (OPVs). Specifically, we evaluate the effectiveness of solution-cast poly(3-hexylthiophene-2,5-diyl) (P3HT) as an electron donor paired with BsubPc derivatives relative to vacuum-deposited sexithiophene (α-6T). By using fullerene (C60 ), boron subphthalocyanine chloride (Cl-BsubPc), and hexachloro boron subphthalocyanine chloride (Cl-Cl6 BsubPc) as electron acceptors, we find that devices made with α-6T outperform those with P3HT. However, the two thiophene-based materials show the same performance trends. Given the preservation of these trends, we can recommend either option for assessing the potential of new BsubPc derivatives; P3HT as a solution-cast electron-donor layer or α-6T as a vacuum-deposited alternative.
在本研究中，我们考虑选择一种标准的供电子材料与亚酞菁硼（BsubPcs）配对，以快速评估新型BsubPc衍生物作为有机光伏器件（OPV）中电子受体材料的可行性。具体而言，相对于真空沉积的六噻吩（α-6T），我们评估溶液浇铸的聚（3-己基噻吩-2,5-二亚基）（P3HT）作为与BsubPc衍生物配对的电子供体的有效性。通过使用富勒烯（C60）、氯化亚酞菁硼（Cl-BsubPc）和六氯氯化亚酞菁硼（Cl-Cl6 BsubPc）作为电子受体，我们发现用α-6T制成的器件优于用P3HT制成的器件。然而，这两种基于噻吩的材料表现出相同的性能趋势。鉴于这些趋势的保留，我们可以推荐任何一种用于评估新型BsubPc衍生物潜力的方法；P3HT作为溶液浇铸的电子供体层，或α-6T作为真空沉积的替代物。
