Flexible photovoltaic cells: no highest, only higher

According to the "Scientific Times" report, the development potential of the roll-up display and flexible solar cells in the future will be extremely large. But for solar cells, a very important point is the protective layer. The protective layer can protect the solar cell from oxygen and water vapor, thereby increasing the service life of the cell. Therefore, the protective layer is very important.

Scientists say that the films of solar cells have something in common with potato chips. They all need a thin film to cut off water vapor and air. Like the protective layer of potato chips, it can keep it crisp and fresh, and the cell sheet also needs such a protective film to protect it from the environment, so as to maintain long-term effectiveness. Most glass layers play an important role in the protection of solar cells. Prof. Klaus Noller of the Fraunhofer Institute describes the advantages of thin films: These thin films or protective layers are very flexible and lightweight, and can increase the yield and reduce the production costs of the components.

But this is not the purpose of this study. Dr Klaus Noller and Dr Sabine amberg from the Fraunhofer Institute have been working with the research team for 20 years. They have adopted a material based on modified alkoxides. Protective film. This created a paint film with silica as a protective coating. This combination allows solar cells to be effectively protected.
