The MoO_x/MoS₂ thin films were manufactured on conducting glass (FTO) from the ethanolic mixture of colloidal molybdenum disulfide (MoS₂) and molybdenum oxides (MoO_x) by electrophoretic deposition method and were used for counter electrode of quantum dot solar cells. Different ramp-rate conditions for electrophoretic deposition as well as bias potential were investigated in an attempt to get the highest possible electrocatalytic activity of polysulfide (S^2-/S_n^2-) redox couple. In this research, interestingly, by simply using CdS/CdSe/ZnS photoanode and polysulfide electrolyte under 1000 W.m⁻² AM 1.5 G illumination, the power conversion efficiency of MoO_x/MoS₂-counter-electrode-based QDSC was achieved up to 2.01%, which was double compared to platinum-based counter electrode of QDSCs.

用于量子点太阳能电池中无铂对电极的 MoOx/MoS2 薄膜的电泳共沉积

MoO _x /MoS ₂薄膜是由胶体二硫化钼（MoS ₂）和氧化钼（MoO _x）的乙醇混合物通过电泳沉积法在导电玻璃（FTO）上制备的，用于量子点太阳能电池的对电极. 为了获得多硫化物（S ^2- /S _n ^2-）氧化还原对的最高可能的电催化活性，研究了电泳沉积的不同斜坡速率条件以及偏置电位。在这项研究中，有趣的是，通过简单地使用 CdS/CdSe/ZnS 光阳极和 1000 Wm ^-2下的多硫化物电解质AM 1.5 G光照下，MoO _x /MoS ₂ -对电极基QDSC的功率转换效率高达2.01%，是QDSCs铂基对电极的两倍。
