Gratzel的染料敏化太阳能电池（DSSC）可以很容易地将阳光转化为电能，吸引了全球科学家的广泛关注。DSSC的制造效率受到迄今为止准固体（QS）电解质的缓慢制造（类似于3.5-24小时）的极大限制。在这项研究中，新的复合材料的二氧化硅气凝胶与石墨烯（GR），多壁碳纳米管，或聚苯胺提出了在制造的QS状态电解质。这些复合材料的形态进行了表征。用SiO2气凝胶作为DSSC的QS电解质的凝胶可以在近似3 s内快速固化。使用丝网印刷技术，这些QS电解质可以很容易地用于构建QS-DSSC，以提供高效率和高稳定性。详细研究了复合材料中QS-DSSC的光伏参数和界面电荷转移电阻。具体地，由GR（SiO2@GR）作为凝胶组成的SiO2气凝胶可以极大地提高QS-DSSC的性能，最高达8.25%。这可能是这些SiO2气凝胶复合电解质可以提供一个快速的固化过程中制备的QS状态的DSSC，这可能是有用的，以促进DSSC的发展，为未来的工业化。
Gratzel's dye-sensitized solar cells (DSSCs) can readily convert sunlight into electricity, attracting considerable attention of global scientists. The fabrication efficiency of DSSCs was greatly limited by the slow fabrication (similar to 3.5-24 h) of quasi-solid (QS) electrolytes to date. In this study, novel composites of SiO2 aerogel with graphene (GR), multi-walled carbon nanotubes, or polyaniline were proposed in the fabrication of QS-state electrolytes. The morphology of these composites was characterized. The gels with SiO2 aerogels as QS electrolytes of DSSCs can be rapidly cured in similar to 3 s. Using the screen-printing technology, these QS electrolytes can be readily utilized to construct the QS-DSSC to provide high efficiency and great stability. The photovoltaic parameters and interfacial chargetransfer resistances of the QS-DSSC incorporated with our synthetic composites were investigated in detail. Specifically, the SiO2 aerogel composed of GR (SiO2@GR) as a gel can greatly improve the performance of QS-DSSCs up to 8.25%. It is likely that these SiO2 aerogel composite electrolytes could provide a rapid curing process in the preparation of QS-state DSSCs, which might be useful to promote the development of DSSCs for future industrialization.
