Perovskite solar cells (PSCs) have appeared as an encouraging photovoltaic technology due to their high efficacy and low fabrication cost. However, their stability and scalability are hampered by charge recombination and intricate multilayer architectures. Using HTL-free design, this work explores reduced PSCs designs with the goal of reducing recombination losses and enhancing the overall device performance. Optimized ETL-only and HTL-free topologies may substantially decline the interfacial recombination and progress in charge extraction, according to numerical simulations conducted with SCAPS-1D. The FTO/α-Fe2O3/CH3NH3PbI3/Au device achieves a high power conversion efficiency (PCE) of 2... More >

In overall world the major issues now days are dumping of waste materials. The dumping of waste material in environment causes harmful disease and pollutes the surrounding areas. This research aims to employ industrial waste materials like waste foundry sand (8 %, 16 %, and 24 %) and lime (3 %, 6 %, and 9 %) in the stabilisation of clayey soil so the combined mixture is being utilized as a sub-grade. On waste foundry sand and lime, various tests such as compaction, particle size distribution, Atterberg's limits, specific gravity and California bearing ratio were performed. According to the research, the addition of 16 percent waste foundry sand and 6 percent lime produces the highest dry den... More >

The present study delves into an eco-friendly and scalable method for creating zinc oxide (ZnO) nanoparticles using extract from Piper betle leaves. By harnessing the natural bio-reductive and capping abilities of the phytochemicals found in P. betle, the ZnO nanoparticles formed a hexagonal wurtzite structure, with an average crystallite size of about 20.3 nm, as confirmed by XRD analysis. The UV–Visible spectroscopy results showed a notable blue shift in absorption, leading to an estimated band gap of 4.10 eV, which is linked to quantum confinement effects. FTIR spectra confirmed the presence of biomolecules on the surface, while SEM imaging displayed quasi-spherical polycrystalline part... More >

This study focuses on the green synthesis of iron oxide (Fe2O3) nanoparticles using guava leaf extract as a reducing agent. The methodology involves the extraction of guava leaves to create an aqueous reagent solution, followed by the synthesis of Fe2O3 nanoparticles through a series of processes including centrifugation and annealing. The synthesis procedure involved mixing the guava extract with an iron nitrate solution, stirring, and allowing the formation of nanoparticles, which were subsequently annealed at 600°C. Characterization of the resulting nanoparticles was carried out using X-ray diffraction (XRD), revealing a rhombohedral structure with an average crystallite size of approxim... More >
