Abstract The translation of unparalleled efficiency from the lab-scale devices to practical-scale flexible modules affords a huge performance loss for perovskite solar cells (PSCs). degradation is attributed brittleness and discrepancy crystal growth upon different substrates. Inspired by robust crystallization structure vertebrae, herein, we employ conductive glued polymer between indium tin oxide layers, which simultaneously facilitates oriented sticks devices.
