Опубликована: Янв. 26, 2024

Within one decade, lead halide perovskite solar cells have reached power conversion efficiencies (PCEs) compatible with that of silicon cells. While in the beginning, they suffered from short device lifetimes, those also been strongly improved over time. However, their content toxic still poses a risk environmental pollution and human health on exposure. The double (DP) Cs 2 AgBiBr 6 offers potential to be lead‐free alternative light‐harvesting material. Herein, fabrication hole transport material (HTM)‐free ‐based is presented, which DP surface modified via n ‐butylammonium posttreatment create 2D/3D mixed interface. Additionally, commonly utilized metal electrode HTM are substituted carbon black back (CBE) consisting up‐cycled biowaste. Through interface modification, charge recombination suppressed, band alignment at perovskite/CBE density functional theory calculations reveal an increasing 2D modification thickness enhances probability for holes located close interface, further supporting extraction. Overall, PCE HTM‐free through implementation low‐cost end‐of‐waste strategy.

Abstract Nonlinear optical materials hold great promise for applications in advanced opto‐/opto‐electronic devices. However, achieving a substantial nonlinear absorption coefficient and modulation depth concurrently remains challenging. This study proposes an effective strategy enhancing the response of through construction hybrid inorganic–organic superlattices via convenient organic intercalation. Synthesizing SnS 2 intercalated with various tetra‐alkylammonium cations, it is revealed that optimized sample (SnS /CTA: cetyltrimethylammonium, CTA + ) exhibits enhancement across broad wavelength range (from 515 to 1550 nm) diverse processes (saturable absorption, two‐photon three‐photon absorption). Specifically, /CTA demonstrates third‐order (9.847 ± 0.084) × 10 3 cm GW −1 69% under laser excitation at 800 nm. Under nm excitation, displays fifth‐order (45.3 1.2) −2 62% depth. Notably, these values surpass those majority non‐exfoliated materials. Structural, spectral, density functional theory calculations indicate no induced structure defects post‐organic The observed bandgap reduction attributed electron injection associated molecule calculated performance enhancement, based on dielectric reduction, qualitatively aligns experimental findings.

Abstract Improving the efficiency of tin‐based perovskite solar cells (TPSCs) is significantly hindered by energy level mismatch and weak interactions at interface between fullerene‐based electron transport layers (ETLs). In this study, four well‐defined multidentate fullerene molecules with 3, 4, 5, 6 diethylmalonate groups, labeled as FM3, FM4, FM5, FM6 are synthesized, employed interfacial in TPSCs. It observed that increasing number functional groups these fullerenes leads to shallower lowest unoccupied molecular orbital (LUMO) levels enhance chemical interactions. Notably, FM5 exhibits a suitable robust interaction perovskite, effectively enhancing extraction defect passivation. Additionally, unique structure allows exposed carbon cage be tightly stacked upper after facilitating efficient charge transfer protecting from moisture oxygen damage. As result, FM5‐based device achieves champion 15.05%, surpassing PCBM‐based (11.77%), FM3‐based (13.54%), FM4‐based (14.34%), FM6‐based (13.75%) devices. Moreover, unencapsulated excellent stability, maintaining over 90% its initial even 300 h air exposure.
