英文摘要	a facile spray deposition method was developed to prepare a high-quality perovskite layer under ambient conditions. however, the performance is expected to be further improved with substrate and the hole transport layer (htl) optimization and device structure, for instance. mwcnts with incorporated spiro-ometad exhibited j(sc) of 22.13 ma cm(-2) and pce of 10.42%. to infer the origin of the increasing j(sc) and pce, the optical absorption performance, charge transfer and recombination performance were investigated tau, r-ct, r-rec as a function of voltage and eis measurements revealed the lower transfer resistance and recombination rate in pscs with mwcnts compared with the pscs without mwcnts. the increased resistance in dark conditions and the dark j-v curves explain the slight changes in the v-oc. the sem images showed that there were no mwcnts aggregated on the surface of the spiro/mwcnts composite layer and part of mwcnts was uncovered by spiro-ometad at the interface of htm and au electrode. the decreased i-d/i-g ratio from 0.90 to 0.68 demonstrated the increased interaction between mwcnts and spiro-ometad.
