Vertical 3D hybrid CE was prepared by the MoS2 nanosheets anchored on the CNTs.
Directly grown CNTs provided a high-speed pathway to promote charge transport.
CNTs promoted the loading of MoS2 nanosheets to enhance electrocatalytic activities.
Nanosheet-like layered MoS2 with plenty active sites promoted the redox abilities.
The DSSC with vertically aligned MoS2/CNT 3D hybrid CE obtained a PCE of 7.83%.
