However, the transmittance of currently available conductive glass is around 87%, and its conductivity is relatively low, limiting its application. Currently available conductive glass is primarily used in the upper layer (transparent conductive glass) of automotive electrochromic rearview mirrors and as the conductive layer of electrochromic glass, but is not suitable for use in solar cells. Utility Model Content
