Saving energy in the building sector and automotive industry is a major global socio-economic target in energy efficiency as well as from environmental viewpoint. Electrochomic smart windows are the future of the building envelope. It allows people to dynamically control the heat and light flow into a building depending on the needs of the occupant and the changing outside environment. NiO has been studied intensively for used as an active material for anodically coloring electrode in electrochromic devices. The potential application of nanostructured material depends upon its properties. It...
