The fully printable perovskite solar cells was developed with triple mesoscopic layers, where the TiO2 nanocrystalline layer, the ZrO2 spacer layer and the mesoporous carbon counter electrode were printed on a single conductive substrate layer by layer, and then filled with an organic-inorganic perovskite materials under atmospheric condition. The bifunctional molecules were introduced into the perovskite materials to enhance the performance of fully printable perovskite solar cells. The results indicated that the interface engineering plays a key role of stability with directing the crystal formation and growth during the infiltration and precipitation of the perovskite within the mesoporous oxide scaffold. The fully printable mesoscopic perovskite solar cell presents no obvious decay within over 1000h light soaking and high efficiency of more than 16%. Meanwhile, the characterization of the mesoscopic perovskite solar cells under the UV light soaking condition was performed. Moreover, 3600 cm2 mesoscopic perovskite solar panel was also fabricated. These results offer a promising prospect for its commercial application.
