Despite their complementary properties, the synergistic integration of nonlinear graphene quantum dots (GQDs) and dye sensitizers remains underexplored. In this study, an efficient hybrid photoelectrode is deposited by sensitizing fluorescent nonlinear GQDs with N3 dye on a plasmonic Au@TiO2 substrate. The hydrothermal method is used to systematically engineer blue, brownish, and bluish-green, fluorescent N-doped, Cl-doped, and N,Cl-codoped GQDs. The N,Cl-GQDs exhibit self-defocusing behavior, indicating a negative nonlinear refractive index and distinct nonlinear optical properties. Nonlinear GQDs serve as light-harvesting antenna to optimize charge separation dynamics, with N3 dye molecules acting as energy acceptors in the coupled system. The spectral overlap between N,Cl-codoped GQDs and N3 dye maximizes fluorescence resonance energy transfer (FRET) efficiency and electron injection while suppressing recombination. Under AM1.5G illumination, the optimized photoelectrode achieves a Voc of 0.705 V, a Jsc of 7.9 mA/cm2, a fill factor of 70%, and a power conversion efficiency (η) of 3.9%, demonstrating improvements over reference N3-based solar cells.

This article systematically reviews recent advances in interface engineering for high-performance PSCs, which focus on key regulation strategies at the hole transport layer (HTL)/perovskite, electron transport layer (ETL)/perovskite, and electrode interfaces. These strategies include energy level alignment optimization, defect passivation, suppression of ion migration, improvement of interfacial wettability, and construction of multifunctional composite interfaces. In addition, the roles of advanced characterization techniques, such as GIWAXS, time-of-flight secondary ion mass spectrometry (TOF-SIMS), and TRPL, and theoretical simulation methods are summarized.

The resulting Type-II junctions noticeably broaden visible-light absorption, accelerate charge migration, and suppress electron–hole recombination. Electron withdrawing cyano groups introduced in situ effectively tune the band structure, create favorable energy alignment for directional electron transfer, and enrich surface active sites. In situ irradiation X-ray photoelectron spectroscopy reveals a dualactivesite system between cyano group and ZNF, confirming efficient photoinduced charge separation.

Herein, we propose an air-annealing process coupled with a precise humidity control strategy to prepare cesium-based 2D perovskite films featuring regular low-n-value phase distribution and vertical crystal orientation. The moisture in air serves to facilitate the rapid decomposition of dimethylamine iodide (DMAI), while also accelerating the ordered insertion of spacer cations phenethylamine (PEA+) by hydrogen bonding, ultimately achieving additive-free and passivator-free PEA2Cs3Pb4I13 PSCs with a power conversion efficiency (PCE) of 15.52% (5.33% efficiency of PSCs in N2). The air-annealed devices can retain 90% of the initial PCE after 1300-h storage in N2 and over 80% of its initial PCE after 1200 h of continuous maximum power point tracking under illumination.

In this work, a 4-(pyridin-4-yl)triphenylamine (TPA-Py) with pyridine anchor group was employed for intergrain bulk modification of double-cation CsCH(NH2)2PbI3 perovskite absorbers to enhance thermal stability. Through coordination and dipole–dipole interactions, nitrogen-containing fragments (diphenylamine and pyridine) of TPA-Py passivate uncoordinated cations and improve the phase resilience of perovskite films against segregation. This resulted in a power conversion efficiency of 21.3% with a high open-circuit voltage of 1.14 V. Notable impact of self-assembled monolayer incorporated into the bulk of the perovskite film manifested in a huge improvement of thermal stability at 85°C (ISOS-D-2). TPA-Py modification extended the T80 lifetime to ≈700 h compared to only 200 h for the reference under harsh heating stress in ambient conditions. In-depth analysis using photoinduced voltage transients and admittance spectroscopy after different stress periods revealed the screening of ion migration (0.45 eV) for devices with TPA-Py.

All-perovskite tandem solar cells (APTSCs) provide a promising route to overcome these limitations through tunable bandgaps, compositional flexibility, and low-temperature processing. In particular, triple-junction (3J) APTSCs show the potential to surpass 40% efficiency by stacking wide-, intermediate-, and narrow-bandgap (WBG, IBG, NBG) subcells with complementary spectral utilization. This review summarizes recent advances toward stable and efficient 3J APTSCs, including halide homogenization and additive-assisted crystallization for WBG absorbers, oxidation control and interface passivation for NBG subcells, and key considerations for IBG subcells, particularly the need for thermally stable surface passivation. In addition, we discuss the critical role of optoelectronic modeling at the 3J device level for managing parasitic optical losses and achieving accurate current matching across multilayer stacks. Collectively, these developments underscore the technological potential of all-perovskite 3J tandems as a scalable and sustainable platform for next-generation photovoltaics.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 4","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146680379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid two-step deposition route has emerged as a promising method for achieving conformal coatings on micron-scale textures, a critical feature for perovskite/silicon tandem photovoltaics. In this work, we present a fully sequential route, wherein the inorganic materials CsCl and PbI2 are deposited separately, allowing for facile industrial implementation as compared to the commonly codeposited inorganic scaffold. Microstructural analysis reveals a change in preferred crystal orientation of the PbI2 platelets with codeposition resulting in horizontal growth, whereas sequential deposition promotes vertical growth with a secondary tilted orientation. Elemental mapping of the final perovskite absorber shows homogeneous distribution of Cs, formamidinium, and I, while Pb and Cl largely retain their initial scaffold positions. PSCs fabricated via sequential deposition of the inorganic scaffold demonstrate improved process repeatability and reach an efficiency of 20.3%, ranking among the highest reported efficiencies for wide-bandgap hybrid two-step processed PSCs.
