“…These electrical conductors needs to be transparent and are of large interest not only in electrochromics but also in variety of devices such as thin film solar cells, light emitting devices, display devices of various types, etc., thus there are numerous reviews covering the field of transparent conductors [40,41,42,43,[44][45][46][47][48][49][50][51][52][53], and here we focus on the materials related work to be used in EC smart window. In the EC smart windows two transparent conductors are required on either side between the glass substrate and the electrochromic layer and is possibly the most expensive part of the EC window, so lots of attention is needed [3].…”

ABSTRACT:Strategies for incorporating energy-efficiency requirements into building standards have been implemented by governments in developed countries in order to introduce the concept of green nanotechnology. Substituting regular glass windows in residential/commercial buildings with smart windows is the objective. The smart window is to function as electric dimming glass that is to be built with innovative nanomaterial based membranes/ coatings. Currently, the regular windows are made of glass and curtains/blinds are used to block sun light; eliminating such elements is of importance due to its limited functionality. Though these curtains/blinds blocks UV and prevents sun light illumination inside the rooms, but there are additional issues such as health hazards (e.g. dust and germ collection especially in hospitals) relating to asthma problems, disposal/recycling issues, regular cost, and maintenance which are some of the possible glitches. The smart window is expected to block harmful UV light and provide controlled privacy while also eliminating the problems related to curtains/blinds. Electrochromic (EC) smart windows are already in use that varies the throughput of visible light by electrical voltage or by solar energy application and are able to provide energy efficiency and indoor comfort. These smart windows comprises of electrochromic materials such as LixWO2.89 and HxNiO2 as cathodic and anodic oxide films, respectively, and other complex polymers, which are complicated to create, expensive and some are hazardous in nature. Nanocellulose (achieved from wood/pulp product) is already being used in flexible electronics, so nanomaterial membrane based suspended particle device (SPD) technology for smart window is a probable alternative to EC devices, but still under research. This paper reviews, introduces and discusses the present situation of both (EC and SPD) options for the state-of-the-art smart windows and its applications while also provide ample references to current literature of particular relevance and thereby, hopefully, an easy entrance to the research field. Also the paper presents an outlook for an innovative technology for smart-windows with SPD-EC technology to work as dimming glass on voltage application while also induce the capability of solar applications in smart windows leading to green nanotechnology in buildings.

“…In recent years, the number of articles and patents on electrochromic materials and devices, ECDs, known for the modulation of their optical properties under an applied voltage, have significantly increased in the literature [1][2][3][4][5][6][7][8][9]. Indeed, ECDs are widely investigated in different commercial applications [10-13] such as displays, rearview mirrors and smart windows for buildings [14,15].…”
