Abstract: The transparent electrode prepared on the three-dimensional substrate surface has the performance advantages of high scattering and large specific surface area. Based on this, on the one hand, it can improve the monochromatic incident photon-to-electron conversion efficiency of the solar cell, on the other hand, the large specific surface area can improve the charge storage of the transparent capacitor. At present, the research that has been carried out is mainly the transparent electrode technology of metal nanowires based on silver nanowires. However, on the one hand, the cost of metal nanowires is high, on the other hand, the characteristics of metal itself and the use of semiconductor materials have certain limitations. In contrast, the cost of carbon-based materials（mainly carbon nanotubes and graphene） is low. At the same time, carbon and the current main semiconductor material silicon are the same main group element, so compared with metal materials, it is more advantageous to combine with semiconductor materials. Based on the above contents, the preparation of carbon-based materials on three-dimensional substrate surface has more far-reaching research significance.
