研究了水基多硫化物电解质中甲醇含量对SILAR法制备的TiO(2)/CdS/CdSe量子点敏化太阳能电池(QDSSC)的影响。此外，还研究了用ZnS外层涂覆介孔QD敏化膜的效果。使用时间分辨光谱测量来测量电荷复合反应。这些研究揭示了在多硫化物电解质中使用 ZnS 层和甲醇对控制这些器件内的电荷转移过程以及最终对整体电池性能产生的协同有益影响。
The effect of methanol content in water based polysulfide electrolytes in TiO(2)/CdS/CdSe quantum dot sensitized solar cells (QDSSCs) prepared by the SILAR method was studied. In addition, the effect of coating the mesoporous QD sensitized films with ZnS outer layers was investigated. Charge recombination reactions were measured using time resolved spectroscopic measurements. These studies reveal a synergistically beneficial effect from using ZnS layers and methanol in the polysulfide electrolyte on the control of charge transfer processes within these devices and ultimately on overall cell performance.
