Due to recent advances in communication systems, dielectric and magnetic ceramics (ferrites) are attractive for use devices. Spinel-type ferrites were the first material utilized microwave devices; however, yttrium iron garnet (YIG) has low losses is exploited many applications. Owing its high Faraday rotation, YIG films magneto-optical This study intends examine research trends scientific progress on highly cited papers discussing published between 2012 2022 using a bibliometric method. A...
The lack of control in voltage overshoot, transient response, and steady state error are major issues that frequently encountered a grid-connected photovoltaic (PV) system, resulting poor power quality performance damages to the overall system. This paper presents strategy for an inverter three-phase PV system consists panel, boost converter, DC link, inverter, resistor-inductor (RL) filter is connected utility grid through source inverter. main objective proposed improve by optimising...
Abstract A numerical analysis of a CdTe/Si dual-junction solar cell in terms defect density introduced at various energy levels the absorber layer is provided. The impact concentration analyzed against thickness CdTe layer, and variation top bottom bandgaps studied. results show that thin film with defects between 10 14 15 cm −3 acceptable for designed cell. variations concentrations indicate open circuit voltage, short current density, efficiency (ƞ) are more affected by higher thickness....
Solar energy is popular worldwide due to the escalating demand for renewable and clean solutions. The inherent low power conversion efficiency of solar panels highlights indispensable role a charge controller in optimizing transfers from panel storage battery. Traditional buck converters are marred by considerable losses freewheeling diodes, thus making synchronous converter, which necessitates protection against reverse current battery panel. During irradiation, voltage typically falls...

Because performance current is several...
Perovskite solar cell (PSC) technologies have recently become a popular research topic. The hole transport layers (HTL) are important in establishing stable and efficient PSC by regulating charge absorption, interlayer recombination losses, band alignment. Spiro-OMeTAD was extensively used as the HTL to fabricate highly PSCs. Despite having benefit of providing high PCEs, it is costly, hazardous ecology, cannot provide efficiencies lack additional additives that can reduce their stabilities....
The study used magnetron sputtering to investigate the growth of cadmium telluride (CdTe) thin films on surface treated n-type silicon (n-Si) substrates. n-Si substrates were textured using potassium hydroxide (KOH) before sputter deposition CdTe. This was followed by chloride treatment reduce strain at interface CdTe and Si, which is caused incompatible lattice thermal expansion mismatch (CTE). X-ray diffraction (XRD) analysis showed that lowest FWHM dislocation densities obtained for...
