我们通过将一维（1D）和二维（2D）混合的二硫化钼-单壁碳纳米管（MoS 2-SWCNT）异质结构应用于钙钛矿太阳能电池来展示二硫化钼（MoS 2）的优异空穴传输能力。CVD合成的MoS 2-SWCNT同时用作空穴传输层和阳极。与裸单壁碳纳米管相比，在单壁碳纳米管周围包裹1D/2D MoS 2提高了近20%的功率转换效率（PCE），这是由于填充因子的显著增强。应用2，2 ′，7，7 ′-四-9，9 ′-螺二芴（spiro-MeO 2）后，PCE达到15.0%。
We demonstrate the excellent hole-transporting ability of molybdenum disulfide (MoS2) by applying one-dimensional (1D) and two-dimensional (2D) mixed MoS2-single-walled carbon nanotube (MoS2-SWCNT) heterostructures to perovskite solar cells. The CVD-synthesized MoS2-SWCNT functions as both the hole transport layer and anode at the same time. Compared with bare SWCNT, the wrapping of 1D/2D MoS2 around SWCNT improved the power conversion efficiency (PCE) by almost 20%, owing to the substantial enhancement of the fill factor. A PCE of 15.0% has been achieved after the application of 2,2′,7,7′-Tetrakis-9,9′-spirobifluorene (spiro-MeOTAD).
