A ternary and composite MoIn₂S₄@CNTs counter electrode (CE) with a hedgehog ball structure was synthesized by using a facile one-step hydrothermal method. The composite MoIn₂S₄@CNTs film possesses large specific surface area through N₂ adsorption-desorption isotherms test, which is advantageous to adsorb more electrolyte and provide larger active contact area for the electrode. In addition, the composite MoIn₂S₄@CNTs CE exhibits low charge transfer resistance and fine electrocatalytic ability made from a series of electrochemical tests including cyclic voltammetry, electrochemical impedance, and Tafel curves. Under optimal conditions, the DSSC based on the MoIn₂S₄@CNTs-2 composite CE achieves an impressive power conversion efficiency as high as 8.38%, which remarkably exceeds that of the DSSCs with the MoIn₂S₄ CE (7.44%) and the Pt electrode (8.01%). The current work provides a simplified preparation process for the DSSCs.

采用一种简易的一步水热法合成了具有刺猬球结构的三元复合MoIn ₂ S ₄ @CNTs对电极（CE）。通过N ₂吸附-解吸等温线测试，复合MoIn ₂ S ₄ @CNTs膜具有较大的比表面积，有利于吸附更多的电解质，并为电极提供更大的有效接触面积。此外，复合MoIn ₂ S ₄通过一系列的电化学测试，包括循环伏安法，电化学阻抗和Tafel曲线，@ CNTs CE表现出低的电荷转移阻力和优良的电催化能力。在最佳条件下，基于MoIn ₂ S ₄ @ CNTs-2复合CE的DSSC达到了令人印象深刻的功率转换效率，高达8.38％，明显超过了MoIn ₂ S ₄ CE的DSSC （7.44％）和铂电极（8.01％）。当前的工作为DSSC提供了简化的准备过程。
