Author:Roro, Kittessa T; Tile, N; Yalisi, B; De Gama, M; Wittes, T; Roberts, T; Forbes, ADate:May 2011A sol-gel technique has been established at a laboratory scale for low cost production of high efficient selective solar absorbers comprising a composite material of nano-structured carbon in a nickel oxide matrix. In order for these materials ...Read more
Author:Makiwa, G; Katumba, G; Olumekor, LDate:Aug 2008The authors present a cheaper and environmentally friendly method to fabricate efficient spectrally selective solar absorber materials. The sol-gel technique was used to fabricate carbon-silica (C-SiO2) and carbon-nickel oxide (C-NiO) composite ...Read more
