对电极（CE）材料具有低成本、高导电性和电催化活性的特点，是染料敏化太阳能电池（DSSC）实现实际应用的关键之一。为了解决这个问题，通过原位聚合配置了由氧化石墨烯（GO）诱导的柱状双面聚苯胺（PANI）纳米锥阵列（PANI/GO），并揭示了 DSSC 的低成本 CE 的电化学行为。采用GO片作为基底和结构导向剂可以有效诱导PANI阵列的均匀和垂直生长，从而产生自由和开放的网络。这种独特的结构还能够缩短离子扩散路径并为电解质提供大的接触面积。并且，可以实现 8.19 ± 0.08% 的高功率转换效率，优于 Pt 和 PANI 参考材料。此外，制成的 PANI/GO CE 还具有出色的电化学稳定性。本策略提供了一种简单而有效的方法来设计用于 DSSC 的高效和快速传质催化剂以及用于其他能量存储/转换的电极材料。
Counter electrode (CE) materials, featuring low cost, high electrical conductivity and electrocatalytic activity, are one of the key points to achieve practical application of dye-sensitized solar cells (DSSCs). To tackle with this issue, the pillared and double-faced polyaniline (PANI) nanocone arrays induced by graphene oxide (GO) (PANI/GO) are configured throughin-situpolymerization, and the electrochemical behavior as the low-cost CE for DSSCs is revealed. The GO sheets adopted as a substrate and structure-directing agent could effectively induce the uniform and vertical growth of PANI arrays, thus producing a free and open networks. This unique structure is further capable of shortening the ionic diffusion path and providing the large contactable area to the electrolyte. And, a high power conversion efficiency of 8.19 ± 0.08% can be achieved, being superior to those of Pt and PANI references. Moreover, the as-made PANI/GO CE also delivers an outstanding electrochemical stability. The present strategy provides a simple yet efficient method to engineer the high-efficiency and fast mass-transport catalyst for DSSCs and electrode materials for other energy storage/conversion.
