CdTe Photovolataic Glass Cadmium Solar Telluride (CdTe) photovoltaic glass is a type of solar glass that incorporates thin-film photovoltaic technology based on the semiconductor compound cadmium telluride. CdTe is one of the materials used in thin-film solar cells, and when applied to glass surfaces, it creates a transparent or semi-transparent layer that can convert sunlight into electricity.
