Electrochromic Glass Design with Solar Energy

Abstract

With the effect of the use of non-renewable energy sources, our world is facing the danger of global warming. The use of fossil fuels increases the rate of carbon dioxide emitted into the atmosphere, and thus, global warming, unfortunately, brings climate changes with it. Minimizing this danger can only be achieved by turning humanity towards renewable energy sources. Solar energy is a reliable, environmentally friendly and inexpensive source. The aim of this study is to perform the electrochromic glass by using solar energy without any electricity costs and thus to encourage people to more renewable energy technologies. In this study, it is desired to present a new technology design that is an alternative to the classical window glasses used in our country by using solar energy. The solar panel converts the sun's energy into electrical energy by using solar energy, and with this electrical energy, the opaque electrochromic glass changes color and becomes transparent. Thus, the glass makes the interior of the room show with this color change. This system, which works with a photovoltaic panel, operates the electrochromic glass with solar energy without the need for extra energy. For example, with this system, it also eliminates the need for curtains or roller blinds used in working and living areas and provide ease of use according to the desired conditions. This system can be used not only for this purpose, but also anywhere that is required for smart glass design and has solar energy potential. For this study, electrochromic smart glass obtained by placing polymer dispersed liquid crystal (PDLC) smart material and this material was sandwiched between indium tin oxide window films with the help of Polyvinyl butyral (PVB) layer. This electrochromic glass system is designed by connecting the connection cable and the onoff switch cable to the photovoltaic panel. In this study, electrochromic glass performance was tried to be analyzed depending on the exposure time of the photovoltaic panel in the sun.
