我们开发了高度灵活和透明的碳纳米管（CNT）网络电极制备的一个简单的刷涂方法生产成本效益的柔性有机太阳能电池（FOSC）。通过使用由尼龙原纤维制成的常规漆刷在聚对苯二甲酸乙二醇酯（PET）基底上直接快速刷涂CNT，我们实现了具有286 Ω/平方的低薄层电阻、78.45%的高扩散透射率和室温下上级机械柔性的多孔CNT网络电极。的电，光学和机械性能的刷涂的CNT电极进行了研究作为一个功能的重复刷涂周期的数量。特别地，刷涂的CNT电极在几种测试模式中显示出出色的柔性，包括外弯曲、内弯曲、扭曲和拉伸，这是柔性电极的关键要求。值得注意的是，刷涂的CNT网状电极在动态疲劳测试期间在5 mm的外弯曲半径和内弯曲半径内具有恒定的电阻变化（Δ R/R-0）。在刷涂的CNT电极上制造的FOSC显示出1.632%的功率转换效率，表明使用刷涂的CNT电极作为用于基于印刷的低成本FOSC的成本有效的柔性和透明电极的可能性。(C)2013爱思唯尔有限公司保留所有权利。
We developed highly flexible and transparent carbon nanotube (CNT) network electrodes prepared by a simple brush-painting method for the production of cost-effective flexible organic solar cells (FOSCs). By direct, rapid brush-painting of CNTs on a polyethylene terephthalate (PET) substrate using a conventional paintbrush made of nylon fibrils, we achieved percolated CNT network electrodes with a low sheet resistance of 286 Omega/square, a high diffusive transmittance of 78.45%, and superior mechanical flexibility at room temperature. The electrical, optical, and mechanical properties of the brush-painted CNT electrodes were investigated as a function of the number of repeated brush-painting cycles. In particular, brush-painted CNT electrodes showed outstanding flexibility in several test modes, including outer bending, inner bending, twisting and stretching, which are critical requirements in flexible electrodes. Notably, the brush-painted CNT network electrodes had a constant resistance change (Delta R/R-0) within outer and inner bending radii of 5 mm during dynamic fatigue testing. FOSCs fabricated on the brush-painted CNT electrode showed a power conversion efficiency of 1.632%, indicating the possibility of using brush-painted CNT electrodes as cost-effective flexible and transparent electrodes for printing-based low cost FOSCs.
