We demonstrate the excellent hole-transporting ability of molybdenum disulfide (MoS 2 ) by applying one-dimensional (1D) and two-dimensional (2D) mixed MoS 2 -single-walled carbon nanotube (MoS 2 -SWCNT) heterostructures to perovskite solar cells. The CVD-synthesized MoS 2 -SWCNT functions as both the hole transport layer and anode at the same time. Compared with bare SWCNT, the wrapping of 1D/2D MoS 2 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).

MoS 2-碳纳米管异质结构作为钙钛矿太阳能电池中的有效空穴传输剂和导体

我们通过将一维（1D）和二维（2D）混合MoS 2-单壁碳纳米管（MoS 2 -SWCNT）异质结构应用于钙钛矿太阳能电池，证明了二硫化钼（MoS 2）的出色的空穴传输能力。CVD合成的MoS 2 -SWCNT同时用作空穴传输层和阳极。与裸SWCNT相比，由于填充因子的大幅提高，将1D / 2D MoS 2包裹在SWCNT周围可将功率转换效率（PCE）提高近20％。在应用2,2'，7,7'-Tetrakis-9,9'-螺双芴（spiro-MeOTAD）后，PCE已达到15.0％。
