本文介绍了一种新的使用喷涂制造的有机太阳能电池的织物可穿戴能源收集应用。在这项工作中使用的标准编织65/ 35聚酯棉织物的表面粗糙度是150 μ m的数量级，这是减少到几微米的丝网印刷的界面层。这种具有降低的表面粗糙度的预处理织物基底被用作含有多层电极和活性材料的喷涂织物有机太阳能电池的目标基底。在织物基底上制造的完全喷涂的光伏（PV）器件已被成功地证明具有与基于玻璃的对应物相当的功率转换效率。所有PV器件均在模拟AM 1.5条件下进行表征。通过扫描电子显微镜（SEM）和原子力显微镜（AFM）检查器件的形貌。这种方法可能适用于将PV器件低成本集成到服装和其他装饰纺织品中。
This paper presents the novel use of spray-coating to fabricate organic solar cells on fabrics for wearable energy harvesting applications. The surface roughness of a standard woven 65/ 35 polyester cotton fabric used in this work is of the order of 150 mu m and this is reduced to a few microns by a screen printed interface layer. This pre-treated fabric substrate with reduced surface roughness was used as the target substrate for the spray-coated fabric organic solar cells that contain multiple layers of electrodes and active materials. Fully spray-coated photovoltaic (PV) devices fabricated on fabric substrates have been successfully demonstrated with power conversion efficiency comparable to that of their glass based counterparts. All PV devices are characterised under simulated AM 1.5 conditions. Device morphologies were examined by scanning electron microscopy (SEM) and atomic force microscopy (AFM). This approach is potentially suitable for the low cost integration of PV devices into clothing and other decorative textiles.
