For the perovskite solar cells（PSCs）, the performance of the PSCs has become the focus of the research by improving the quality of the perovskite absorption *** far, the performance of the large-area PSCs is lower than that of small-area *** the paper, the experiments were designed to improve the photovoltaic performance of the large-area PSCs by improved processing *** we investigated the optoelectronic properties of the prototypical CH3NH3PbI3（MAPbI3） further modulated by introducing other extrinsic ions（specifically co-doped Cland 5-AVA）.Moreover, we used inorganic electron extraction layer to achieve very rapid photo-generated carrier extraction eliminating local structural defects over large ***, we fabricated a best-performing perovskite solar cell based on co-doping Clanionand5-AVA cation which uses a double layer of mesoporous TiO2 and ZrO2 as a scaffold infiltrated with perovskite and does not require a hole-conducting *** experiment results indicated that an average efficiency of double-mesoporous layer-based devices with co-doping Cl anion and 5-AVA cation was obtained with exceeding 50% enhancement, compared to that of pure single-mesoporous layer-based device.
