开发具有高电催化活性的透明对电极是双面染料敏化太阳能电池的一个长期目标。为了加速电荷转移和增加透明电极的活性位点，采用回流法合成了硫化钼（MoS 2）修饰的苯胺配合物，并通过原位聚合制备了透明聚苯胺（PANi）-MoS 2配合物电极。初步结果表明，PANi-MoS 2复合物CE对I3−还原的电催化活性显著增强，这是由于PANi（N原子）和MoS 2（Mo原子）之间通过金属（dπ）-氮（pπ）反键相互作用进行的快速电荷转移所致.基于PANi-6 wt‰ MoS 2复合物CE的双面DSSC具有高的光学透明性、对I3 −的电催化还原、I−/I3−氧化还原对的上级电荷转移能力，正面照射时的最大功率转换效率为7.99%，背面照射时为3.40%，两者照射时为9.71%，均高于正面照射，对于采用PANi CE的DSSC，后效率和双效率分别为6.37%、1.78%和7.50%。高的光学透明度和电催化活性沿着以及简单的制备、相对低的成本和可扩展性证明了PANi-MoS 2络合物作为双面DSSC中的稳健CE的潜在用途。
Exploration of cost-effective and transparent counter electrodes (CEs) with high electrocatalytic activity has been a persistent objective of bifacial dye-sensitized solar cells (DSSCs) development. Here, with an aim of accelerating charge transfer and increasing the active sites of a transparent CE, molybdenum sulfide (MoS2) decorated aniline complexes are synthesized by a reflux technique and subsequently in-situ polymerized for transparent polyaniline (PANi)-MoS2complex CEs for efficient bifacial DSSCs. The preliminary results indicate that the electrocatalytic activity toward I3−reduction of PANi-MoS2complex CE is dramatically enhanced due to the fast charge transfer between PANi (N atoms) and MoS2(Mo atoms) by the metal (dπ)-nitrogen (pπ) antibonding interaction. Owing to the high optical transparency, electrocatalytic reduction toward I3−species, superior charge-transfer ability for I−/I3−redox couples, the bifacial DSSCs based on PANi-6 wt‰ MoS2complexes CE yield a maximum power conversion efficiency of 7.99% from front irradiation, 3.40% from rear irradiation and 9.71% from both irradiation, which are higher than front, rear and both efficiencies of 6.37%, 1.78% and 7.50% for DSSC employing PANi CE, respectively. The high optical transparency and electrocatalytic activity along with simple preparation, relatively low cost and scalability demonstrate the potential use of PANi-MoS2complex as a robust CE in bifacial DSSCs.
