【 摘 要 】

MoS2 microspheres were synthesized by a hydrothermal method using sodium molybdate as the molybdenum source and thiourea as the sulfur source, were used as the counter electrode of dye-sensitized solar cells. This paper discussed the influence of the thiourea concentration on the preparation and photoelectric properties of MoS2 microspheres. The results show that the crystallinity, microsphere structure, photoelectric conversion efficiency and catalytic activity of MoS2 reach the best state when the Mo/S molar ratio is 1:4. Therefore, the thiourea concentration has an important effect on the structure, morphology and photoelectric properties of MoS2. The conclusion will provide the basis for us to improve the electrode material performance of MoS2 to replace Pt counter electrode.
