2D perovskites are one of the proposed strategies to enhance the moisture resistance, since the larger organic cations can act as a natural barrier. Nevertheless, 2D perovskites hinder the charge transport in certain directions, reducing the solar cell power conversion efficiency. We present a nanostructured mixed-dimensionality approach to overcome the charge transport limitation, obtaining power conversion efficiencies over 9%.
