采用自组装单分子膜和化学浴沉积(CBD)相结合的方法，将硫化镉(Cd)量子点组装到二氧化钛介孔薄膜上，用于染料敏化太阳能电池(DSSC)。首先在二氧化钛表面自组装了胶体硫化镉量子点。然后引入CBD来补充掺杂量，提高CDS量子点在二氧化钛表面的覆盖率。预组装的硫化镉量子点在CBD过程中充当成核点，形成具有能够抑制注入电子复合的界面结构的硫化镉纳米薄膜。利用该策略实现了量子点敏化的DSC的效率高达1.35%。(C)2007年美国物理研究所。
Two methods, coupling self-assembled monolayer and chemical bath deposition (CBD), were utilized to assemble cadmium sulfide (CdS) quantum dots (QDs) onto mesoporous TiO2 films for dye-sensitized solar cell (DSSC) applications. Colloidal CdS QDs were first self-assembled on the TiO2 surface. CBD was then introduced to replenish the incorporated amount and increase the coverage ratio of CdS QDs on the TiO2 surface. The preassembled CdS QDs act as nucleation sites in the CBD process, forming a CdS nanofilm with an interfacial structure capable of inhibiting the recombination of injected electrons. An efficiency as high as 1.35% for the QD-sensitized DSSC was achieved using the present strategy. (c) 2007 American Institute of Physics.
