Two systems with an oxygen di-vacancy are generated and we test the diffusion and the effects of increasing the number of Li in the most stable configurations. The oxygen vacancy in the first and second layers facilitates the diffusion of Li. We found that Li migration is stopped at the bulk-like defect-free layers in the direction normal to the surface. The DOS of the lithiated system shows that the changes take place at the lower end of the conduction band. Li becomes Li⁺¹, and the charge density difference diagrams show the redistribution of charge to the neighboring atoms. When Li is intercalated at the (110) surface, the most important change occurs at the Fermi level (E_F) and is caused by the interaction between Ti 3d and Li 2s orbitals. When N-lithium (N = 1, 2, 3) is considered in the defective system, the bonding order of Li atoms increases with the amount of adsorbed alkali metal atoms. In the case of Li intercalation, the sum of the bond order of all atoms is higher than in the adsorbed case, while for the Li atom, it is almost twice as high. When more Lithium is considered, new Li-O bonds are formed. Ab initio molecular dynamics simulations (AIMD) are performed, to check the stability of the system.

Phase-I is produced using a single laser scan strategy with a narrow fluence window. Phase-II is optimally produced using four sequential laser scan passes, each with a specific fluence. The rationale for the first pass was to disrupt carbon atoms, the second and third exposures were to gently modify this disrupted phase, and the fourth pass was to anneal the final structure. No characteristic graphene peaks were observed in Raman spectra for Phase-I, however, this phase surprisingly showed higher conductivity when compared with Phase-II.

The alkyl chain in the surface ligands significantly affect external stimuli depending on their length.

However, the photo-active <em>α</em>-phase FAPbI₃ suffers the poor structural stability, easily transforming to photo-inactive <em>δ</em>-phase FAPbI₃ at room temperature, a process that is accelerated by the moisture. While numerous methods have been proposed to address this issue, most efforts have relied on glove-box conditions, substrate heating, or air-knife flow. To date, few studies have reported a strategy for fabricating highly efficient FAPbI₃ perovskite solar cells (PSCs) under humid conditions. In this study, we are the first to demonstrate the fabrication of FAPbI₃ PSCs using a one-step solution deposition method in a relative humidity of 70 % without the need for auxiliary processes or equipment, achieved through the addition of a highly volatile solvent and the incorporation of methacrylic acid (MAA) into the perovskite layer. The addition of the volatile solvent enables the fabrication of FAPbI₃ perovskite in a high-moisture environment without adversely affecting the phase transformation process. The MAA incorporation not only decreases pinholes in the perovskite layer but also passivates the deep-level defects through the interaction of carboxyl groups with formamidinium cations, resulting in a low trap-state density, high charge recombination resistance, and long charge lifetime. The thermal treatment used for phase transformation of the perovskite also induces the polymerization of MAA, which further improves the long-term stability of PSCs. This dual-functional passivation approach enables PSCs to achieve high power conversion efficiency, surpassing many previously reported values for PSCs fabricated without additional processes or specialized equipment, even under highly humid conditions.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"25 ","pages":"Article 100683"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143182001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Covalent and noncovalent modifications are the two main techniques for functionalizing epoxy resins. The addition of hydroxyl (‒OH), amino (‒NH₂), or carboxyl (‒COOH) groups through covalent functionalization to the ERs enhances their reactivity, adhesion, and solubility of epoxy resins. Noncovalent functionalization entails adding nanomaterials such as metals, metal oxides, and carbon allotropes to the resin matrix. Functionalized ERs are more effective anti-corrosive materials in the aqueous phase and the coating. Growing solubility and more polar functional groups are responsible for FERs' improved potential to guard against corrosion in the aqueous phase. Mechanical strength, chemical and thermal stability, and corrosion resistance are traits that these alterations improve. Significant improvements in corrosion resistance have been demonstrated when epoxy resin coatings with inorganic (TiO₂, CeO₂, SiO₂, Al₂O₃, h-BN, lanthanides, etc.) and organic (G, GO, CNTs, PANI, MXenes, MOFs, PDA, BIM, LDH, polymers, etc.) additives are used.
