We demonstrate the enhancement of pore-filling and wettability of gel electrolyte in quasi-solid-state dye-sensitized solar cells (DSSCs) by developing a kinetically driven electrolyte infiltration approach, in which the air purging provides the driving force. This method renders fast electrolyte diffusion throughout the three-dimensional TiO2 nanoparticle network, promising for large-area device fabrication. In addition, for the first time we incorporate multiwalled carbon nanotubes into the anode of quasi-solid-state DSSCs to improve the charge transfer efficiency and fill factor. These advancements finally generate an efficiency exceeding 7.0%, much higher than the device efficiency of 5.5% fabricated by the conventional method.
我们通过开发一种动力学驱动的电解质渗透方法来提高准固态染料敏化太阳能电池(DSSC)中的孔填充和润湿性,其中空气吹扫提供驱动力。该方法使电解质在整个三维 TiO2 纳米颗粒网络中快速扩散,有望用于大面积器件制造。此外,我们首次将多壁碳纳米管引入准固态 DSSC 的阳极,以提高电荷转移效率和填充因子。这些改进最终产生了超过 7.0%的效率,远高于传统方法制造的 5.5%的器件效率。
