Hi,
I am working on fabrication of the tin perovskite solar cells. Tin perovskite solar cells are known for their low stability in ambient conditions due to intensive oxidation of tin. Therefore, it is highly advisable to encapsulate these devices after fabrication. I am curious to know how to encapsulate tin perovskite solar devices with low temperature thermoplastic sealant?
I am looking for suggestions to effectively encapsulate solar devices. Thank you!
Before encapsulation you can coat your solar cells with silicon dioxide layer using spin on techniques. Such layer will make the bare side sealed against effect of oxygen and moisture.
We developed a novel encapsulation method named three flat plates modules.
For such method please follow the link: Article A.A. Elshazly, A. Zekry , M.A. El-Koosy and M.s. Farid, “Thr...
and the book chapter:Chapter Solar Cells and Arrays

The encapsulation of the devices can be done with a cavity on a glass cover filled with a desicant to absorb moisture using a special glue to seal on the devices. The procedure must be handled inside a nitrogen or argon filled glovebox.
Hi, You can "embed" your device in between two glasses and a TPO film making a "sandwich" using on the edges an edge sealant (better if butyl based). The contacts you can carry out of the sandwich through the butyl edge sealant without too many "headaches".
This "sandwich" will be then vacuum laminated at the right T and process time. But you need to be equipped with some sort of vacuum laminator or build your own...
Another possibility is to do like it was done for test cells of dye sensitised solar cells (dssc) or Grätzel cells. Those cells are known to be VERY sensitive to moisture and other oxidative compounds and have also a liquid electrolyte (to make things easier ;)): encapsulate your device in between 2 pieces of glass using surlyn as encapsulant. You do not need vacuum but just temperature (performing such exercise under atmosphere (N2) will be recommended if you want to survive longer.
Good luck!
