Annealing effect of hybrid solar cells based on poly (3-hexylthiophene) and zinc-oxide nanostructures
Motaung, David; Malgas, Gerald; Ray, Suprakas S.; Arendse, Christopher (Elsevier, 2013)The structural growth and optical and photovoltaic properties of the organic–inorganic hybrid structures of zinc oxide (ZnO)-nanorods/poly-3-hexylthiophene (P3HT) and two variations of organic polymer blends of ZnO/ ... -
Characterization of silicon nitride thin films deposited by hot-wire CVD at low gas flow rates
Oliphant, Clive J.; Arendse, Christopher; Muller, Theophillus F.G.; Knoesen, Dirk (Elsevier, 2013)We examined the chemical, structural, mechanical and optical properties of amorphous hydrogenatedsilicon nitride thin films deposited by hot-wire chemical vapour deposition using SiH4, NH3and H2gases at total flow rates ... -
Chemical Vapor Deposited Mixed Metal Halide Perovskite Thin Films
Magubane, Siphesihle; Arendse, Christopher; Ngqoloda, Siphelo (Materials, 2021)In this article, we used a two-step chemical vapor deposition (CVD) method to synthesize methylammonium lead-tin triiodide perovskite films, MAPb1−xSnxI3, with x varying from 0 to 1. We successfully controlled the concentration ... -
Comparative study: the effect of annealing conditions on the properties of P3HT:PCBM blends
Motaung, David E.; Malgas, Gerald; Nkosi, Steven S.; Mhlongo, Gugu H.; Mwakikunga, Bonex W.; Malwela, Thomas; Arendse, Christopher; Muller, Theophillus F. G.; Cummings, Franscious R. (Springer Verlag, 2013)This paper presents a detailed study on the role of various annealing treatments on organic poly(3-hexylthiophene) and [6]-phenyl-C61-butyric acid methyl ester blends under different experimental conditions. A combination ... -
Effect of the annealing atmosphere on the layer interdiffusion in Pd/Ti/Pd multilayer stacks deposited on pure Ti and Ti-alloy substrates
Halindintwali, Sylvain; Donald, Earl; Cummings, Franscious; Arendse, Christopher (University of the Western Cape, 2019)Pd(50 nm)/Ti(25 nm)/Pd(50 nm) multilayer stack has been deposited on Ti and Ti6Al4V substrates; we have studied the intermixing of layers upon annealing at the hydrogenation temperature of 550 °C, under vacuum, H/Ar gas ... -
Effects of p-type-metal-doping (Ba, Cs, and Y) of the compact-TiO2 electron transporting layer on the photovoltaic properties of n-i-p perovskite solar cells
Nwankwo, Uba Nwankwo; Arendse, Christopher; Maaza, Malik (Springer, 2023)Tailoring of charge transport properties of the electron transport layer (ETL) in solution-processible solar cells is continuously addressed not only for the performance enhancements in perovskite solar cells but also in ... -
Infuence of Synthesis Method on Structural, Morphological, Magnetic, and Antimicrobial Properties of Fe‑Ag Nanoparticles
Noukelag, Sandrine Kamdoum; Ngqoloda, Siphelo; Mewa‑Ngongang, Maxwell; Kotsedi, Lebogang; Razanamahandry, Lovasoa Christine; Ntwamp, Seteno; Arendse, Christopher; Maaza, Malik (Springer, 2023)This contribution reports on the development of two versatile and efcient methods, namely the green and gamma radiolysis for Fe-Ag nanoparticles (NPs) synthesis, characterization, and further their growth inhibition potential ... -
Self-catalytic growth of tin oxide nanowires by chemical vapor deposition process
Thabethe, Bongani; Malgas, Gerald; Motaung, David; Malwela, Thomas; Arendse, Christopher (Hindawi, 2013)We report on the synthesis of tin oxide (SnO2) nanowires by a chemical vapor deposition (CVD) process. Commercially bought SnO nanopowders were vaporized at 1050∘C for 30 minutes with argon gas continuously passing through ... -
Visible and IR photoluminescence of c-FeSi@a–Si core–shell nano-fibres produced by vapour transport
Thabethe, Sibongiseni; Linganiso, Ella; Motaung, David; Mashapa, Matete G.; Nkosi, Steven; Arendse, Christopher; Mwakikung, Bonex W. (Elsevier, 2013)The procedures for the synthesis of amorphous ε-FeSi/Sicore–shell nanofibres by vapour transport in a CVD configuration are reported. Crystallite studies by the Williamson-Hall method show the sizes to be typically about ...
