Abstract：With the rise of the Internet of Things technology, wearable electronic devices have been rapidly developed, and their power supply problems are becoming increasingly prominent. Traditional solar cells are mostly flat structure, not suitable for comfortable wear. In recent years, dye-sensitized solar cells with fiber structure have the characteristics of flexibility, light weight and braided, and are expected to become a promising wearable mobile power supply. In order to prepare long size and low defect dye-sensitized solar cells with fiber structure, a continuous electroplating device was designed with copper wire as the base, and a layer of manganese metal was successfully plated on the surface of copper wire by electroplating process, which solved the problem of mismatch of copper wire energy levels. Secondly, a continuous electrodeposition device of seed layer was designed to prepare a dense and uniform zinc oxide seed layer, which provides qualified seed seeds for the growth of zinc oxide nanoarrays. Then, the continuous coating process of electrolyte layer was improved by electric heating assisted film forming method, and the smooth and uniform cuprous iodide electrolyte was prepared, and the fiber photoanode was obtained. Finally, the fiber structure solar cell is successfully assembled with gold wire as the counter electrode, and the conversion efficiency of 1.3% is achieved after optimization. Further use of flying shuttle, embroidery and other methods, fiber batteries are prepared into wearable solar power fabric, and can be applied to smart home, outdoor sports and other scenarios, providing a good solution for the future commercial application of wearable energy fabric.
