Highly-flexible, ITO-free dye-sensitized solar cells (DSSCs) are fabricated in a simple, all-solution-based, facile, and controllable way. A double mesh structure is applied to DSSCs, and the design principles, especially scale parameters, are analyzed delicately to ensure the power conversion efficiency and mechanical flexibility of the device. The good flexibility of mesh-based DSSCs is verified by systematic bending tests compared to conventional flexible DSSCs based on PET/ITO or metal foil substrates. Commercial carbon ink is used as a counter electrode material, and it is proved to be low-cost and efficient. The double mesh structure design provides an attractive strategy toward the development of flexible and wearable electrochemical energy supplies.
高度灵活的无ITO染料敏化太阳能电池（DSSC）以简单、全溶液基、简便且可控的方式制造。将双网格结构应用于DSSC，并对设计原理，特别是尺度参数进行了精细分析，以确保器件的功率转换效率和机械柔韧性。与基于PET/ITO或金属箔基板的传统柔性DSSC相比，通过系统的弯曲测试验证了基于网格的DSSC具有良好的柔韧性。使用商用碳油墨作为对电极材料，证明其成本低且效率高。双网格结构设计为柔性和可穿戴电化学能源供应的发展提供了一种有吸引力的策略。
