Herein, we develop a self-floating photocatalyst, Pt@MBP, consisting of platinum (Pt) nanoparticles anchored on triazine-biphenyl conjugated polymer nanosheets. Pt@MBP is prepared through calcination of a melamine-biphenyl-4,4′-dicarboxylic acid supramolecular precursor followed by photodeposition of Pt. Owing to its floatable feature, Pt@MBP effectively captures atmospheric O2 at the gas–liquid interface and enhances visible-light harvesting. The ultrathin MBP nanosheets facilitate charge separation and migration, while the well-dispersed Pt nanoparticles function as electron sinks and catalytic centers for O2 adsorption and activation, thereby lowering the energy barrier for the oxygen reduction (ORR) pathway. As a result, Pt@MBP achieves a H2O2 production rate of 2352 μmol g−1 h−1 in pure water. This work establishes a rational design of self-floating polymer photocatalysts for efficient solar-to-chemical conversion.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 5","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563958","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}

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.

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.
