Perovskite solar cell achieves higher stability with new tin oxide layer - eviltoast
Using atomic layer deposition, a research team from the City University of Hong Kong has created an an oxygen-deficient tin oxide layer to replace the more common fullerene electron transport layer in perovskite solar cells. The result is a 25%-efficient device that is able to retain around 95% of its efficiency after 2,000 h.

    The research paper documents how the team’s fabricated cell achieved a power conversion efficiency of over 25% after optimizing oxygen vacancy defects within the tin oxide layer. The cell also demonstrated superior stability compared to traditional perovskite solar cells, as it retained over 95% of its efficiency after 2,000 hours of continuous operation under rigorous test conditions.
