现代电子技术的快速发展对柔性、可穿戴的能源资源提出了更高的要求。柔性透明导电电极是柔性/可穿戴薄膜太阳能电池的重要组成部分。在这方面，塑料表面的商用氧化铟锡(ITO)虽然存在丰度低、膜脆、红外透过率低、化学稳定性差等缺点，但仍显示出优异的光电性能。另一方面，其他几种无透明导电氧化物(TCO)的透明导电材料，如碳纳米管(CNTs)、石墨烯、金属纳米线(NWS)和导电聚合物，都经历了快速发展来解决这些问题。在这篇专题文章中，概述了几种柔性无TCO薄膜SCs的最新发展，即有机太阳能电池(OSCs)、染料敏化太阳能电池(DSSCs)、钙钛矿型太阳能电池(PERO-SCs)和纤维/线形SCs。柔性无TCO薄膜太阳能电池根据其配置可分为三类：(I)正面照明平面配置；(Ii)背面照明平面配置；(Iii)光纤形状太阳能电池(FSSC)。本文重点介绍了柔性无TCO碳纳米管，包括碳纳米管、石墨烯、金属纳米管、金属格栅、导电聚合物、金属纤维和碳基纤维。
The rapid development of the modern electronics gives rise to higher demands of flexible and wearable energy resources. Flexible transparent conducting electrodes (TCEs) are one of the essential components for flexible/wearable thin-film solar cells (SCs). In this regard, commercial indium tin oxide (ITO) on plastics has demonstrated superior optoelectronic performance although some drawbacks, i.e., the low abundance, film brittleness, low infrared transmittance, and poor chemical stability remain. On the other hand, several other transparent conducting oxide (TCO)-free transparent conductive materials, such as carbon nanotubes (CNTs), graphene, metallic nanowires (NWs), and conducting polymers, have experienced a rapid development to address these issues. In this feature article, an overview over the latest development of several flexible TCO-free thin film SCs, i.e., organic solar cells (OSCs), dye-sensitized solar cells (DSSCs), perovskite solar cells (pero-SCs), and fiber/wire-shaped SCs is provided. Three groups of flexible TCO-free thin film solar cells can be categorized according to their configurations: (i) front-side illuminated planar configuration; (ii) back-side illuminated planar configuration, and (iii) fiber-shaped solar cells (FSSCs). The article is focused on flexible TCO-free TCEs, including CNTs, graphene, metallic NW/nanotroughs, metallic grids, conducting polymers, metallic fiber, and carbon based fibers.
