| 英文摘要 | perovskite solar cells (pvscs) have recently emerged as a very attractive option in film photovoltaics. both solvent-engineering techniques and electron transport layer (etl) properties are necessary for high-performance pvscs. herein, we report a one-step spin-coating approach for the preparation of uniform and dense perovskite layers, using a mixed solvent of dimethylacetamide (dmac) and n-methyl-2-pyrrolidone (nmp) followed by exposure to toluene to induce crystallization. we also developed a simple and quantitative method to improve the traditional compact tio2 etl properties and device performance based on zn precursor doping. the effect of zn-doped tio2 was investigated using atomic force microscopy, ultraviolet-visible spectra, photoluminescence, and open-circuit photovoltage decays. the results indicate that zn-doped tio2 provides a better interface between the etl and perovskite layer than non-doped tio2. light zn doping (2 vol%) was found to be the most effective additive, and the average power conversion efficiency improved from 13.61% to 15.25%. |
