Perovskite solar cell achieves higher stability with new tin oxide layer

5 comments

Have they fixed the whole only lasting for a few weeks thing? That was the last issue i heard with perovskite cells.
- Sounds like it lasts closer to 100 days now, that’s an improvement.
- 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
Whats the efficiency and how does time effect it?
- 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.
