Abstract

We reported a facile solution-processed method to fabricate a MoS _x anode buffer layer through thermal decomposition of (NH ₄)₂MoS₄. Organic solar cells (OSCs) based on in situ growth MoS_x as the anode buffer layer showed impressive improvements, and the power conversion efficiency was higher than that of conventional PEDOT:PSS-based device. The MoS_x films obtained at different temperatures and the corresponding device performance were systematically studied. The results indicated that both MoS₃ and MoS₂ were beneficial to the device performance. MoS₃ could result in higher V_oc, while MoS₂ could lead to higher J_sc. Our results proved that, apart from MoO₃, molybdenum sulfides and Mo⁴⁺ were also promising candidates for the anode buffer materials in OSCs.
