“…[26] Although a-6T has recently been established as an electrondonor layer for pairing with Cl-BsubPc, [3] this oligomeric thiophene is not easily solution-cast. [27] However,p oly(3-hexylthiophene-2,5-diyl) (P3HT,F igure 1a) is an easily solution-cast polymeric thiophene. [28] P3HT has been as tandard organic electronic material for al ong time, and has been widely used in BHJ OPVs as an electron-donor material paired with PC 61 BM.…”

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.
