Introduction. Many transition metal oxides have been investigated regarding their potential for use in electrochromic applications [1–16].Among these oxides, tungsten oxide (WO 3) is the most commonly used inorganic electrochromic compound due to its many favorable properties, including a high capacity for reversible Li + insertion, a high coloration efficiency, good reversibility Calculation of solar and light transmittance.
