Solar energy has developed as a feasible clean energy source, with electrochemical water splitting and photocatalytic water purification offering promising techniques for creating clean energy and tackling environmental challenges. This research presents an innovative hybrid catalyst, designated as ZIF-67-NC@CNS/MWCNT, which consists of N-doped Zeolite Imidazolate Framework-67 (ZIF-67) derived carbon and CoNi₂S₄ with Multi-Walled Carbon Nanotubes (MWCNT), utilizing a Metal-Organic Framework (MOF) as a template. This distinctive structure demonstrates exceptional multifunctional electrochemical performance in many applications, including Dye-Sensitized Solar Cells (DSSCs), Oxygen Evolution Reactions (OER), Hydrogen Evolution Reactions (HER), and photocatalytic degradation of tetracycline (TC). This composite, used as a counter electrode in DSSCs, attained a power conversion efficiency (PCE) of 6.35 %, a short-circuit current density (J_SC) of 12.54 mA cm⁻² and an open-circuit voltage (V_OC) of 0.8 V. The observed increases may be ascribed to reduced peak-to-peak separation, lowered charge transfer resistance, shorter electron lifetimes, and greater exchange current density. The ZIF-67-NC@CNS/MWCNT composite exhibited remarkable bifunctional electrocatalytic activity, with overpotentials of 144 mV and 178 mV at 10 mA cm⁻² for the OER and HER, respectively. Interestingly, the hybrid composite achieved the highest degradation efficiency of 97.56 % against TC under white light irradiation. The synergistic effect of metal sulfides and carbon materials can provide additional electron transmission paths and contact areas, leading to effective I₃⁻ reduction, reduced overpotential, and enhanced degradation efficiency.

This leads to excessive temperatures inside the cell, which reduces the efficiency of the electrical conversion and shortens the life of the cell. Therefore, efficient cooling solutions are needed. In this paper, a novel approach for the cooling of concentrator solar cells is proposed. Compared to the solutions found in the literature, the proposed solution incorporates microchannels into the backside metal contact layer of the solar cell. This way, there are no restrictions regarding the semiconductor material, no decrease in mechanical stability, and no thermal interface material is required. First, the appropriate channel geometry and theoretical performance were determined for a 2 × 2 cm² solar cell using Siemens FloTherm computational fluid dynamics and an in-house analytical modelling tool written in ANSI C. The paper describes the step-by-step iterations of the design and the manufacturing process that were necessary to reach the theoretically calculated ideal performance. Hydrodynamic and thermal measurements were performed generation by generation, taking into account the results obtained from simulation results. For the latest generation, comparing the hydrodynamic properties at a flow rate of 80 cubic centimeters per minute, the difference between the simulated and the average difference of measured pressure drop values is 2.29 %. The measured data confirms that the partial thermal resistance of the microchannel-based cooling device is 0.32 K/W at a maximum applied pressure drop of 1 bar. This means that the temperature increment for a solar cell with a surface area of 4 cm² exposed to a concentration level of 100 suns is only 11.5 K.</div></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"31 ","pages":"Article 101170"},"PeriodicalIF":7.1,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144563930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
