Problems solved by technology

However, the process of forming the protective film is too time-consuming and labor-intensive, has a very high failure rate, and is not suitable for the production of flexible solar cells, because the structure of the protective film will be destroyed under the flexing action, making the The silver wire is in contact with the electrolyte
What's more, due to the additional protective film, the area of ​​the overall protective film / silver wire covers the surface area of ​​the conductive substrate to a considerable extent, which affects the light transmittance of the electrode
[0008] To sum up, the traditional method to reduce the impedance value of the conductive substrate is not only too time-consuming, but also limits the application of dye-sensitized solar cells, which is not ideal
