A generic interface to reduce the efficiency-stability-cost gap of perovskite solar cells

This is the authors' abstract. We don't add key points for this paper.

-doped interface-based perovskite solar cells achieve maximum efficiencies of 21.2% and offer more than 1000 hours of light stability. By eliminating additional ionic dopants, these findings open up the entire class of organics as scalable hole-transporting materials for perovskite solar cells.
