“…The aforementioned resistances in a cell signify its departure from ideality and may have an impact on some of the cell's photovoltaic characteristics, particularly its FF. Series resistance, which may originate from bulk layers, electrodes, and interfaces, represent the solar cell's resistance to charge generation whereas shunt resistance describes a cell's resistance to the recombination process [88]. Clearly, the performance of a solar cell device may be enhanced with lower series resistance and higher shunt resistance.…”

Green energy transition and climate change have gathered significant momentum in the world because of the rising population and increased clean energy demands. For this reason, renewable energy alternatives such as inexhaustible photo energy from the sun appear to be the ultimate solution to the world's energy needs. Formamidinium tin tri‐iodide (HC(NH2)2SnI3)‐based perovskites are found to be more efficient and stable than their methylammonium tin tri‐iodide (MASnI3) counterparts because of its wider bandgap and better temperature stability. A device simulation of FASnI3‐based solar cell is numerically performed using solar cell capacitance simulator (SCAPS‐1D). The focus is to investigate the effect of changing working temperature, metal back contact, absorber thickness, defect density, and doping concentration on the performance of the proposed solar cell device. The optimised solar cell parameters of the proposed solar cell were: short‐circuit current density (Jsc) of 28.45 mAcm−2, open‐circuit voltage (Voc) of 1.0042 V, fill factor of 63.73%, and power conversion efficiency of 18.21% at 300 K, thus, paving the way for novel perovskite solar cells which are environmentally benign because they are lead‐free, have better absorption efficiency, and can be injected into the production work flow for commercial applications.

“…Xu et al prepared a BiVO 4 @MoS 2 core–shell heterojunction by an electrostatic spinning method, and the MoS 2 /BiVO 4 heterojunction could completely degrade RhB solution within 20 min. Melika et al prepared Ag@ZnFe 2 O 4 @TiO 2 composites, which possessed the fastest rate of electron transfer and maximum electron collection efficiency, as well as the highest dye loading capacity and the smallest photoluminescence intensity (charge composite), all of which are obviously conducive to the improvement of the performance of DSSCs (dye-sensitized solar cells). Babu et al prepared a nanorod-structured ZnWO 4 @SnO 2 , which can degrade the TC with an efficiency of 97% in 2 h. Alamier et al prepared ZIF-9 composite MXene Z-type heterojunctions, which can sufficiently help in degradation of 4-chlorophenol.…”

Problems such as bacterial resistance caused by tetracycline antibiotics pose a serious threat to human production and life and ecosystems. We prepared ZnFe 2 O 4 @ZnWO 4 heterojunction nanocomposites using hydrothermal and coprecipitation methods. The micromorphology, structure, and photoelectrochemical properties were analyzed. In combination with the presence of H 2 O 2 , the photo-Fenton activity of the antibiotic tetracycline at high concentration was tested under visible light irradiation, and its catalytic mechanism was investigated. The results showed that the composition of the composite heterojunction improved the catalytic activity of the catalyst. At a pollutant concentration of 50 mg L −1 and pH 5, 30% ZnWO 4 / ZnFe 2 O 4 degraded 92.1% of tetracycline in 60 min with a degradation rate of 0.0295 min −1 , which was 6.7 times higher than that of pure ZnFe 2 O 4 . The results of free radical trapping experiments and electron spin resonance techniques indicated that hydroxyl radical (•OH) and superoxide radical (O 2 − ) played important roles in the photo-Fenton degradation of tetracycline. Notably, the catalyst maintained a high degradation rate (80%) after five cycles. ZnFe 2 O 4 introduced in this article may provide a promising strategy for achieving strong light absorption and is authoritative in meeting future environmental requirements.
