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 ...
The selected 2D material is a ferroelectric fluorinated perovskite known as (4,4-DFPD) 2 PbI 4, (where 4,4-DFPD is 4,4-difluoropiperidinium). The solar cell was built with a substrate made of ...
