“…Organic solar cells (OSCs) have attracted immense attention due to their rich material sources, low cost, lightweight, excellent solution processing, and mechanical flexibility, 1−6 which provide the basis for their roll-to-roll large-scale manufacturing on flexible substrates. 7,8 Although many efforts have been made in the past on the fullerene-based OSCs, 9−11 the highest power conversion efficiencies (PCEs) are restricted below 12%, which is mainly ascribed to some inherent defects of the fullerene acceptors. 12 In recent 5 years, the rapid progress of non-fullerene acceptors (NFAs) 13−18 has largely improved the performance, and the PCEs of the optimal signaljunction OSCs can reach more than 18%.…”

We report a class of high-voltage organic solar cells (OSCs) processed by the environmentally friendly solvent tetrahydrofuran (THF), where four benzotriazole (BTA)-based p-type polymers (PE31, PE32, PE33, and J52-Cl) and a BTA-based small molecule BTA5 are applied as p-type and n-type materials, respectively, according to “Same-A-Strategy” (SAS). The single-junction OSCs based on all four material blends exhibit a high open-circuit voltage (V OC) above 1.10 V. We systematically study the impact of the three different substituents (−OCH3, −F, −Cl) on the BTA unit of the polymer donors. Interestingly, PE31 containing the unsubstituted BTA unit shows the efficient hole transfer and more balanced charge mobilities, thus leading to the highest power conversion efficiency (PCE) of 10.08% with a V OC of 1.11 V and a J SC of 13.68 mA cm–2. Due to the upshifted highest electron-occupied molecular orbital (HOMO) level and the weak crystallinity of the methoxy-substituted polymer PE32, the resulting device shows the lowest PCE of 7.40% with a slightly decreased V OC of 1.10 V. In addition, after the chlorination and fluorination, the HOMO levels of the donor materials PE33 and J52-Cl are gradually downshifted, contributing to increased V OC values of 1.16 and 1.21 V, respectively. Our results prove that an unsubstituted p-type polymer can also afford high voltage and promising performance via non-halogenated solvent processing, which is of great significance for simplifying the synthesis steps and realizing the commercialization of OSCs.
