University of KwaZulu-Natalhttp://hdl.handle.net/10204/6375A dissertation submitted in fulfilment of the requirements for the degree of Master of Science in Physics, School of Chemistry and Physics, University of KwaZulu-NatalHigh efficiency tandem selective solar absorber materials of carbon in nickel oxide (C-NiO) composite were fabricated on an aluminium substrate using a simple and cost effective sol-gel process. The process involved preparation of carbon and nickel oxide precursor sols which were homogeneously mixed to form a final C-NiO precursor sol. The carbon precursor sol was prepared by dissolving sucrose (SUC) in 8 ml of distilled water. The NiO precursor sol was prepared by dissolving 7.5 g nickel acetate in 50 ml ethanol, then adding 6.3 g diethanol amine (DEA) to stabilise the solution followed by addition of a structure directing template of polyethylene glycol (PEG). The final C-NiO precursor sol was spin coated on pre-cleaned aluminium substrate to form thin films which were then heat treated in nitrogen ambient inside a tube furnace.enSolar absorber materialsNickel oxideSol-gelCarbon precursor solNiO precursor solDiethanol amineReportTile, N.
