Herein, we present the synthesis of a novel dopant-free spiro-type fluorine core-based HTM with four ethoxytriisopropylsilane groups (Syl-SC) for inverted planar perovskite solar cells (iPSCs). The thickness of the Syl-SC influences the performance of iPSCs. The best-performing iPSC is achieved with a 0.8 mg/mL Syl-SC solution (ca. 15 nm thick) and exhibits a power conversion efficiency (PCE) of 15.77%, with Jsc = 20.00 mA/cm2, Voc = 1.006 V, and FF = 80.10%. As compared to devices based on PEDOT:PSS, the iPSCs based on Syl-SC exhibit a higher Voc, leading to a higher PCE. Additionally, it has been found that Syl-SC can more effectively suppress charge interfacial recombination in comparison to PEDOT:PSS, which results in an improvement in fill factor. Therefore, Syl-SC, a facilely processed and efficient hole-transporting material, presents a promising cost-effective alternative for inverted perovskite solar cells. info:eu-repo/grantAgreement/ES/AGAUR/2021 SGR01261 info:eu-repo/grantAgreement/ES/DGA/E47-23R info:eu-repo/grantAgreement/ES/DGA-FEDER/E47-20R info:eu-repo/grantAgreement/ES/MICINN/CEX2019-000925-S info:eu-repo/grantAgreement/ES/MICINN/PID2019-104307GB-I00-AEI-10.13039-501100011033 info:eu-repo/grantAgreement/ES/MICINN/PID2019-109389RB-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.4 2023 MATERIALS SCIENCE, MULTIDISCIPLINARY 146 / 439 = 0.333 2023 Q2 T2 NANOSCIENCE & NANOTECHNOLOGY 62 / 141 = 0.44 2023 Q2 T2 CHEMISTRY, MULTIDISCIPLINARY 70 / 231 = 0.303 2023 Q2 T1 PHYSICS, APPLIED 47 / 179 = 0.263 2023 Q2 T1 0.798 2023 Chemical Engineering (miscellaneous) 2023 Q1 Materials Science (miscellaneous) 2023 Q2 8.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sánchez, José G.
