Suppressing Buried Interface Defects for Efficient and Stable Inverted Perovskite Solar Cells

Poly(triarylamine) (PTAA) is typically used as a hole transport layer due to its suitable energy band alignment with the perovskite layer, but its poor permeability to perovskite precursors can easily lead to buried interface defects. In light of this, Professor Li Xuanhua from Northwestern Polytechnical University and colleagues published a paper in Nano Energy, titled … Read more
