Unfortunately, its photocatalytic efficiency has been seriously limited by charge carrier recombination and low reaction dynamics. Here, we report a metal-free BCN photocatalyst achieving highly selective CO2-to-CH4 conversion under visible light without requiring any metal cocatalyst. The exfoliated CN nanosheets can enrich the reaction interface with protons to accelerate the protonation of CO intermediate to further produce CH4. Moreover, B doping not only introduces more reactive defects but also tunes its electronic structure with a more negative conduction band for rapid electron extraction and enhance CO2-to-CH4 conversion. Photocatalytic measurements show that CH4 production rate and CH4/CO ratio are 24 and 13 times higher than those of bulk CN, respectively. The CH4 production rate can also reach 130 and 31 times higher than that of few-layer g-C3N4 (FL-CN) and Cu/FL-CN, respectively. The electron selectivity toward CH4 generation on BCN photocatalysts can reach ≈90%. Furthermore, sunlight driving CO2-to-CH4 conversion on such BCN photocatalysts has also been demonstrated.

Realizing the origin and the mechanism of the trapping and recombination processes enables a smart design strategy of high-performance photovoltaic (PV) technologies. Thin film Cu(In, Ga)Se2 solar cells have been commercially used in the PV community due to their high power conversion efficiency, cost-effectiveness, and chemical stability. In this work, we explore the roles of subgap defect states in carrier trapping, in particular effects of Urbach tails in terms of the recombination mechanism, in Cu(In, Ga)Se2 solar cells via junction-transient spectroscopic techniques. The temperature-dependent Urbach energy (EU) was extracted from transient photocapacitance (TPC) and transient photocurrent (TPI) measurements. Thermal quenching behavior is observed at ~220 K for slightly different optimum Ga concentrations, with activation energies of 0.2–0.3 eV obtained from the thermal quenching model. The thermal and optical activation processes along the defect states are further interpreted using a 1D configuration coordinate model which takes the electron–phonon interaction into consideration.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 8","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202400925","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces the design and synthesis of noble metal (Au, Ag, and Pt) nanoparticle-modified RF resins, with a specific focus on Au-RF due to its exceptional photocatalytic activity. The electronic coupling at the interface between Au nanoparticles and the CO bonds of phenolic hydroxyl groups in RF resin facilitates efficient charge transfer, leading to a remarkable improvement in photocatalytic performance, which is attributed to interfacial interactions rather than surface plasmon resonance effects. The optimized Au-RF composite demonstrates a record photocatalytic H2O2 production rate of 252.28 μmol g−1 h−1 with a solar-chemical conversion efficiency of 1.23% after 6 h, significantly surpassing that of the pristine RF resin.

The adequate water transport induced by photothermal conversion significantly improves the mass transfer of uranyl ions.

In 1 L of seawater, 83.8% of uranyl is extracted after exposure to natural sunlight for 48 h.

However, their commercialization is hindered by stability challenges, including sensitivity to environmental conditions and a critical degradation mechanism known as potential-induced degradation (PID). PID can significantly impair PSC performance within hours under operational conditions. This study investigates PID in 48 triple-cation p-i-n PSCs over 313 h in an inert environment, excluding additional stressors like moisture and oxygen. The PID-stressed devices degraded to 79% of their initial efficiency, primarily driven by losses in short-circuit current density. Time-of-flight secondary ion mass spectroscopy revealed sodium ion migration from soda-lime glass substrates into the perovskite layer. Interestingly, photoluminescence and X-ray diffraction analyses detected no measurable differences between PID-stressed and reference devices, contradicting prior literature that associates PID with perovskite segregation and decomposition. These findings challenge the conventional understanding of PID, suggesting that environmental factors such as oxygen and moisture might exacerbate degradation effects. This work provides critical insights into the intrinsic mechanisms of PID under controlled conditions and highlights the need for further research into the interplay between PID and environmental stressors to guide the development of more stable PSC technologies.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 7","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761937","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}

Although Mn0.5Cd0.5S demonstrates considerable potential, its severe stacking issue and insufficient exposure of active sites restrict its application. In this research, by combining Mn0.5Cd0.5S with dodecahedral ZIF-67 and optimizing the interfacial electronic structure, a uniform distribution of Mn0.5Cd0.5S on the surface of ZIF-67 was successfully accomplished. Synthesis of composite materials effectively mitigated the agglomeration phenomenon of Mn0.5Cd0.5S and constructed an S-scheme heterostructure of Mn0.5Cd0.5S/ZIF-67. The resulting composite achieved a hydrogen yield of 677.4 μmol in a lactic acid system, 6.8 times higher than that of pure Mn0.5Cd0.5S. This notable enhancement is attributed to the increased specific surface area of the composite, facilitating greater exposure of the active sites and improving charge transfer efficiency.
