“The efficiency value of 25.32% obtained is record-breaking for 2D/3D perovskite-based perovskite solar cells,” the team said, noting that the device was also able to retain 90% of its initial ...

One proposed strategy to boost the stability, PCEs and reliability of perovskite solar cells entails the passivation of 3D perovskite light-harvesting layers with 2D perovskites. These 2D layers ...
