Our partners at Northestern University have created a coating for perovskite solar cells that help fix their one big achilles heel, long-term stability. 

The coating layer, based on amidinium, was 10 times more resistant to decomposition compared to conventional ammonium-based coatings, and tripled the functional lifetime of the cells!

Much effort has gone into improving the perovskite cell’s efficiency and stability, but the protective coating on the cell has been largely overlooked. The team at Northwestern is working, and finding success in the remedy.
