以咪唑盐基离子液体为连接剂，制备了一种核-壳碳纳米管/导电聚合物复合物，用于碳纳米管的大规模溶液加工。以溶液处理的杂化膜作为对电极的染料敏化太阳能电池（dsc）表现出与使用传统Pt对电极的器件相当的光伏性能。制定的策略非常简单有效，并符合良好的环境要求。水溶性壳层(1)促进了碳纳米管聚集体的分散，将单个碳纳米管带入水溶液，同时保持完整的π共轭结构；(2)降低了电荷注入势垒，实现了较高的光伏性能。本工作为高性能光电和太阳能转换器件的大规模应用铺平了道路。
A core−shell carbon nanotube/conducting polymer hybrid, using an imidazolium-salt-based ionic liquid as a linker, has been developed for large-scale solution processing of CNTs. Dye-sensitized solar cells (DSCs) with the solution processed hybrid film as the counter electrode exhibit comparable photovoltaic performance to that of devices with the conventional Pt counter electrode. A strategy developed is extremely simple and effective with good environmentally compliance. The water-soluble shell (1) promotes dispersion of the CNT aggregates and brings individual CNTs into aqueous solution while maintaining intact π-conjugation structure and (2) leads to a reduced charge injection barrier and realizes high photovoltaic performance. This work paves a way for high-performance optoelectronic and solar energy conversion devices of large-scale applications.
