    Abstract

    Herein, a compact TiO}/Anatase (AT) titania nanoparticles (Ti NPs) bilayer was introduced as an electron transport layer (ETL) by comprising spray pyrolysis (SP) deposition and spin-coating (SC) technique, respectively, in planar perovskite solar cells. A SP-TiO/SC-AT TiO NPs bilayerbased perovskite solar cells are facilitated more efficient electron transport, charge extraction, and low interfacial recombination, and thus leads champion efficiencies up to 17.05% by a significant decrease of J-V hysteresis, presenting almost 12% enhancement compared to the TiO single layer-based counterparts.
