The fully printable perovskite solar cells were developed based on triple mesoscopic layers, where the TiO2 nanocrystalline layer (~1μm), the mesporous spacer layer (~2μm) and the mesocospic counter electrode (~10μm) were screen printed on a single conducting substrate layer by layer, and then filled with an organic-inorganic perovskite materials by simple drop casting method under the atmospheric condition. The bifunctional molecules such as 5-aminopentanoic acid (5-AVA) were introduced into the perovskite materials to enhance the performance of perovskite solar cells. The results indicated that the interface engineering plays a key role of 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 cells present no obvious decay within over 1000h light soaking and high efficiency of more than 15%. Moreover, 5m2 mesoscopic perovskite solar panel will be presented. These results offer a promising prospect for its commercial application.
