Tin-based perovskite solar cells use tin instead of traditional lead for the sake of environmental friendliness. Currently, the key challenges lie in solving the problems of low filling factor, low short-circuit current density, and low open-circuit voltage, which together lead to the overall performance decline in the cells. In this context, we conducted a detailed comparative analysis of the defect state passivation on the surface and interface of tin-based perovskite using phenethylammonium salts (PEAX, X = Cl, I, Br). The results show that doping PEAX in perovskite can improve the morphology, and hydrophobicity of the thin film. At the same time, the carrier recombination lifetime of the device modified by PEAX increases, and the carrier transport lifetime decreases. This indicates that the passivated device has a lower recombination rate and an increased charge transfer rate after illumination, thus reducing carrier recombination. In addition, the embedded electric field and composite resistance of the devices doped with PEAX are increased, and the density of defect states is decreased, which promotes carrier transfer, inhibits dark-state recombination, thereby improving the filling factor, short-circuit current density and open-circuit voltage of the device, and further improving the power conversion efficiency of the device. It is worth noting that among the three PEAX materials used for passivation, PEACl has the best passivation effect, and the highest efficiency of the device after PEACl passivation is 5.74 %. The study provides useful information on passivation methods for tin-based perovskite solar cells.</div></div>","PeriodicalId":378,"journal":{"name":"Journal of Solid State Chemistry","volume":"346 ","pages":"Article 125293"},"PeriodicalIF":3.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143511255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This compound marks the first Tutton-type crystal incorporating Fe²⁺ and Ni²⁺ cations at the divalent sites, offering unexplored possibilities. The Fe/Ni elemental ratio was determined by energy-dispersive X-ray spectroscopy. Structural and geometric parameters obtained from X-ray powder diffraction and Rietveld refinement reveal that the material crystallizes in a monoclinic symmetry within the <em>P</em>2₁/<em>a</em> space group, exhibiting structural isomorphism typical of Tutton salts. SEM images show that the crystal surface grows through the spreading of single layers or the lateral advancement of growth steps. First-principles calculations using density functional theory support the structural and geometric data, experimental Raman and FTIR spectra, and predict an electronic bandgap of approximately 4 eV, derived from the band structure and projected density of states. A complementary theoretical study using 3D Hirshfeld surfaces and 2D fingerprint mappings identifies the H⋯O/O⋯H intermolecular contacts as the primary interactions stabilizing the crystal. The unit cell features a low void percentage (7.42 %), implying high lattice energy between the molecular fragments [NH₄], [SO₄], and [Fe/Ni(H₂O)₆]. Thermally, the crystal remains stable between 300 and 360 K, with phase transformation occurring at higher temperatures, involving full dehydration and the formation of anhydrous salt, followed by a solid-solid phase transition (recrystallization) and material decomposition. A high energy storage density (2.11 GJ/m³) was calculated from dehydration reaction enthalpy. Based on these findings, the mixed crystal (NH₄)₂Fe_0.11Ni_0.89(SO₄)₂(H₂O)₆ is a promising candidate for UV-B optical filters and thermochemical heat storage applications. Overall, the results suggest that occupying the divalent sites of a Tutton structure with different cations allows for tuning electronic, optical, and thermochemical parameters, offering the potential for developing tailored materials.</div></div>","PeriodicalId":378,"journal":{"name":"Journal of Solid State Chemistry","volume":"347 ","pages":"Article 125291"},"PeriodicalIF":3.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143576942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
