Flexible Perovskite Solar Cells: High‐Performance Flexible Perovskite Solar Cells Enabled by Low‐Temperature ALD‐Assisted Surface Passivation (Advanced Optical Materials 24/2018)

In article number 1801153, Yan-Qing Li, Jian-Xin Tang and co-workers demonstrate a facile route to achieving indium-free flexible perovskite solar cells with high efficiency and superior repeated bendability. The performance enhancement benefits from the synergetic interplay of a composite electrode stack, consisting of an electrically conductive silver nanowires network, a sol–gel-derived ZnO smoothing layer, and an atomic-layer-deposited TiO2 passivation layer. This device architecture shows potential for the low-cost roll-to-roll processing of flexible perovskite devices.
