Problems solved by technology

At present, the auxiliary electrode materials on the conductive glass substrates of dye-sensitized solar cells are easily corroded by electrolytes, and organic chemical materials such as UV glue and hot-melt adhesive films used to protect these electrodes or seals will also be corroded by electrolytes for a long time, and more serious It is these organic chemical materials that are easy to age under long-term sunlight, which affects the service life of the battery. Now the packaging and auxiliary electrode protection in the preparation of dye-sensitized solar cells are two processes, which are made separately, which not only affects Increased production efficiency, but also increased production costs
