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.

    Have they fixed the whole only lasting for a few weeks thing? That was the last issue i heard with perovskite cells.

      This seems to be a step towards a solution / a solution.

      Although there’s a company which has supposedly already solved it completely.
      Oxford PV recently had a commercial sale of a perovskite solar panel with a 25 year guarantee

      By adapting the formulation and synthesis of the perovskite and the cell design and encapsulation optimization, Oxford PV succeeded in mitigating stability-related deficits and aims at providing future buyers of their modules with the industry-standard 25 year performance guarantee

      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.
