However, the mechanism and method to regulate such process are rarely reported. Herein, it is found the NaSe_x flux mainly results from the reaction between Se and sodium contained matter (e.g., the soda-lime glass substrate) in the selenization process. Accordingly, co-selenization processes are proposed to regulate NaSe_x-assisted crystallization in which different sodium sources (NaF, Na₂S, etc.) are utilized together with Se. By changing the type of sodium source, the reaction between the sodium source and Se can be altered, which results in NaSe_x flux with different properties. Consequently, the NaSe_x-assisted crystallization of CZTSSe film can be regulated by modifying the properties of NaSe_x flux. When Na₂S is used as sodium source, NaSe_x with optimum properties can be generated. In this condition, the kinetic process for the growth of CZTSSe grains may be modified, which improves the defect formation of the film. Moreover, the NaSe_x flux could penetrate through the grain-boundaries of the crystallized layer. This can enhance the bottom-to-top diffusion of the elements, thus eliminating the fine-grain layer. By using Na₂S/Se co-selenization, both the uniformity and defect properties of the CZTSSe film are improved. The fabricated CZTSSe solar cells achieve the best efficiency of 12.4 % (without anti-reflection coating). This work clarifies the mechanism of the NaSe_x-assisted crystallization, which provides a new route for the crystallization optimization of CZTSSe film.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"292 ","pages":"Article 113771"},"PeriodicalIF":6.3,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144185250","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}

The suggested SAH has been compared to the plain duct SAH without fins at a typical air flow rate of 0.01–0.050 kg/s. The results of this study show that radial fins improve SAH performance characteristics when compared to a plain heater or a heater with longitudinal fins. Furthermore, increasing the number of radial fins and airflow rate improves SAH performance. SAH with five radial fins and an airflow rate of 0.050 kg/s achieves maximum thermal and thermohydraulic performance. The experimental analysis showed that the pressure loss in the proposed SAH with swirl tubes increases by 2.64 % and 16.44 % for AMFR 0.010 kg/s and 0.030 kg/s, respectively. Additionally, radial fins record the highest-pressure loss values, with an increase in pressure loss of almost 11.97 % with maximum average temperature difference about 9.75 °C. Also, this study also demonstrates the effectiveness of various Kolmogorov-Arnold Networks (KAN) models combined with optimization algorithms in predicting the outlet temperature and pressure loss of the investigated heater. The analysis, based on experimental field data, uses five optimization techniques: KAN-CGO (Chaos Game Optimization), KAN-LASHDE (Lagrangian Adaptive Sheepdog Differential Evolution), KAN-AOA (Arithmetic Optimization Algorithm), KAN-HHO (Harris Hawks Optimizer), and KAN-WO (Walrus Optimizer). The KAN-WO model achieved an RMSE of 0.7557, demonstrating that its predictions closely match the experimental data. So, the KAN-WO model emerges as the most reliable for predicting outlet temperature and pressure loss, due to its superior performance, consistency, stability, and ability to generalize.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"291 ","pages":"Article 113726"},"PeriodicalIF":6.3,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138140","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}
