Abstract Perovskite solar cells (PSCs) composed of organic polymer-based hole-transporting materials (HTMs) are considered to be an important strategy in improving the device performance, compete with conventional cells. Yet use such expensive and unstable HTMs, together hygroscopic perovskite structure remains a concern – arguable aspect for prospect onsite photovoltaic (PV) application. Herein, we have demonstrated sustainable fabrication efficient air-stable PSCs invasive plant (...
To improve the performance of PSCs, interfacing green synthesized flake like-ZnO nanostructure have been introduced between ETL/perovskite layer which reduces recombination losses at interface.
In this work, zeolite NaA (RA) and NaX (RX) have been successfully synthesized using rice husk ash it is a low cost synthesis process does not produce environmental hazards. Sodium silicate (SS) extracted from which an alternative silica source for synthesis. The zeolites are prepared by SS the ash, has used as adsorbent CO2 adsorption may help in controlling global warming problems. hydrothermal method without any organic templating agent. FESEM TEM micrographs revealed that RA RX "Ice...
The scientific community is moving toward a green environment using several nontoxic photon‐absorbing materials like tin, germanium, antimony, and bismuth. Bismuth halides have essential advantages low toxicity, Earth abundance, good chemical stability, optoelectronic behavior which make them suitable for lead‐free perovskite solar cells. Herein, streamlined one‐step spin‐coating technique employed DMF to enhance the morphology of thin films based on BiCl 3 perovskite. resulting...
Selenium nanowires have been grown by chemical method. The effect of annealing on the properties prepared selenium has studied. X-ray diffraction studies indicated formation with trigonal phase, and no secondary phase was observed. composition analysis results show that is present in sample. HRTEM images reveal diameter ranging from 30–50 nm length 1-2 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>μ</mml:mi></mml:math>m. found to increase temperature.
Abstract Nanocrystalline nickel oxide (NiO), chromium and cobalt doped NiO nanoparticles have been prepared successfully by chemical precipitation method. NiO, Cr Co-doped characterised using various analytical techniques such as X-ray diffraction, FESEM, HRTEM, UV absorption M-H curves. The average grain size of are 10.33 nm, 9.54 nm 8.70 respectively. absorbance study shows a strong edge at 314.96 308.64 305.37 band gap values 3.936 eV, 4.017 eV 4.060 eV. incorporation into strongly...
Summary By the process of doping in semiconducting nanomaterials, properties materials such as electronic, optical and photochemical can be effectively tuned. Here fluorine doped TiO 2 nanostructures were synthesized by microwave assisted solvothermal technique. The X‐ray diffraction patterns (XRD) Raman analysis results sample exhibits peaks characteristic anatase . From UV‐visible absorption analysis, an increase visible light with no significant change edge was noticed. F found to possess...
