This study investigates the synergistic optimization of printing quality and rheology in front-side fine-grid silver pastes for TOPCon cells. Employing three-stage shear tests (3ITT) and yield stress measurements, we systematically evaluated the effects of A-type short-chain silicone levellers and B-type polyacrylate levellers, across varying dosages, on the paste's initial viscosity, thixotropy, recovery kinetics, and printed grid morphology. Results demonstrate that incorporating 0.2 wt% silicone leveller (A-S-0.2 system) significantly enhances paste recovery, achieving 87 % recovery at 17 s with t<sub>50</sub> < 1 s. This performance markedly surpasses both the control group and B-series samples, ensuring morphological stability during screen printing and pre-sintering. Continuous production-line printing verification revealed that formulations A-S-0.23 and A-S-0.25 achieved aspect ratios of 28.9 % and 34.2 %, respectively. Consequently, series resistance was reduced by 19.2 %–26.9 %, and conversion efficiency increased from 26.19 % to 26.59 %. Analysis indicates that the leveller achieves a precise \"shear-softening–structural-reconstruction\" balance by reducing particle surface energy and suppressing viscosity hysteresis, thereby effectively inhibiting lateral spreading and morphology collapse.

In this work, the photothermal conversion capacities of water-based nanofluids composed of multi nanoparticles (including Ag, TiN and TiO<sub>2</sub>) with different scattering and absorption characteristics are analyzed. Firstly, a coupled numerical calculation model integrating the FEM and the MCRT method is presented, and then the absorption characteristics of radiative energy transfer along the path are predicted by proposed numerical model. Additionally, the photothermal conversion performance of various nanofluids with different distinctive nanoparticles are compared. Meanwhile, different nanofluids are also prepared for the photothermal conversion experiment, which verifies the accuracy of the proposed numerical model. After analyzing the solar-weighted absorption fractions of nanofluids with different radiative properties at different absorption depths, it is found that when the volume fractions of nanoparticles increase, the radiative energy absorbed by the nanofluids will decrease at the saturated absorption condition. This effect becomes more pronounced for the nanofluids with stronger scattering characteristics. When the volume fraction increases from 0.01 % to 0.5 %, the solar-weighted absorption fraction of the TiO<sub>2</sub> nanofluid with a diameter of 100 nm decreases from 0.44 to 0.25. After simulating the photothermal conversion of the nanofluids composed of three material nanoparticles, it is found that the photothermal conversion efficiencies of nanofluids are simultaneously related to the total amount of absorbed radiative energy and its distribution characteristic along the transfer path.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"295 ","pages":"Article 113955"},"PeriodicalIF":6.3,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To support grid stability, PV systems must evolve to be capable of providing frequency regulation and reserve services—including not only down frequency reserve but also up reserve. This latter service requires PV modules to operate away from their maximum power point (MPP), a condition that requires an enhancement in PV module thermal behavior assessment. Consequently, there is a growing need for advanced thermal models that account for electrical operating conditions to ensure accurate temperature prediction under all operating scenarios. While traditional thermal models primarily depend on meteorological inputs, they typically neglect the Electrical Operating Status (EOS). Overlooking this issue can lead to significant prediction errors—up to 5–7 °C—especially during operation away from MPP. The proposed investigation developed an enhanced thermal model incorporating EOS dependency by including the ratio of measured current to the calculated current at MPP as an additional input. Two cases of the Faiman and Sandia models were optimized using Genetic Algorithm, Particle Swarm Optimization, non-linear least squares, and polynomial regression. Optimization is performed using three identical PV systems operating under reference EOS conditions: open circuit, short circuit, and MPP. Results demonstrate that EOS-integrated models significantly improve temperature prediction accuracy. The EOS sensitive models achieved prediction errors as low as 0.1–1.13 % and R<sup>2</sup> values above 0.91, outperforming traditional models that exhibited errors from 2 to 29 %.

Herein, we introduce a five-layer thin-film modulatable thermal emitter based on IST, designed to integrate daytime solar heat collection and nighttime radiative cooling. The average absorptivity in the solar band (0.3–2.5 μm) reaches 0.8 in the amorphous state of this emitter, and the average emissivity at the atmospheric window (3–5 μm, 8–14 μm) is 0.23 and 0.13, respectively; in the crystalline state, the emissivity at the atmospheric window rises to 0.5 and 0.92, which enables the efficient realization of day and night thermal management. Adjusting ZnS thickness allows vivid, angle-stable coloration for architectural and camouflage uses. The emitter maintains stable emissivity under wide-angle incidence and varying refractive conditions, ensuring adaptability. Under AM1.5 illumination, it achieves over 80 % solar absorption with strong photothermal conversion, and net radiative cooling power reaches 70.37 W m<sup>−2</sup> at zero temperature difference. Adding a solar reflector reduces amorphous-state emissivity (0.19 at 3–5 μm, 0.22 at 8–14 μm) and crystalline-state solar absorptivity (0.3 at 0.3–2.5 μm), while increasing crystalline emissivity (0.55 at 3–5 μm, 0.89 at 8–14 μm), enabling daytime cooling and nighttime insulation.
