Study on the Potential Use of Electrochromic Materials for Solar Energy Harvest in Brazil Market

Abstract

This paper presents a review of the characteristics of electrochromic materials, the concepts developed in recent years, the trends and forms of applications of these materials. The purpose of this paper consists in the use of an electrochromic material such as diffusion component and thermal / light control in a tubular system of natural lighting. The interest in the use of this material comes from the fact that them can control the transmission or light reflection, as well as control the transport of heat and selectivity of ultraviolet light. The condition for changing of their selectivity characteristics occur with the application of an electric current. Therefore, your application can spread to different areas, for example the products related to the automotive industry, construction, aerospace, military use, entertainment, among others. This fact arouses interest in research of new applications and the improvement of technique, as proposed in this work is the study of electrochromic material to a tubular lighting system. This proposal comes as a solution to assistance in temperature control and an ambient lighting, contributing to the quality level of illuminance and the climate of the location, factors that directly impact the reduction of the electricity cost.
