In this study a low-temperature processed Cs-doped ZnO nanocrystalline electron transport layer and a narrow-bandgap (~1.70 eV) all-inorganic absorber (Cd-doped CsPbI2.5Br0.5), we report ambient-processed solar cells which exhibit high conversion efficiencies (>19.75%) and stable performance under ambient condition (>300 h). A smooth interface is established by combining spray-deposition of the electron transport layer and injection of hot-air during the perovskite deposition, which crystallizes smooth, compact perovskite thin films directly from solution. |
