Poly Methyl Methacrylate/Room-Temperature Vulcanizing Silicone Rubber Bilayer for Enhancing the Long Term Stability of Perovskite Solar Cells

Case ID:

This invention is a kind of encapsulation package and preparation method toward enhancing the outdoor stability of the perovskite solar cells. This perovskite solar cell with encapsulated bilayer retains more than 80% of the initial efficiency at the environmental condition of 50% moisture and 30°C temperature for more than 1,000 hours.

Perovskite solar cells represent an emerging category of thin film solar cells with very good prospects for becoming a replacement for not only other thin film solar technologies, but also as a substitute for crystalline silicon. Perovskite solar cells can be applied in more traditional fields, such as construction and utility projects, and in emerging, non-typical applications, such as artificial photosynthesis. Shortcomings of current designs are that they are unstable, have a short life span, and perovskite materials are sensitive to factors such as moisture, temperature, and oxygen. Perovskite solar cells with this encapsulated bilayer will be capable of enduring extreme outdoor temperatures for an extended period of time.
