Solar Thin Film Battery

As the name suggests, thin film batteries are made of a thin film into solar cells. They use very little silicon and are easier to reduce costs. At the same time, they are both an efficient energy product and a new type of building material, making it easier to integrate perfectly with buildings. Against the background of continued shortage of silicon raw materials in the international market, thin film solar cells have become a new trend and hot spot in the development of the international photovoltaic market. There are three main types of thin film batteries that have been capable of industrial large-scale production: silicon-based thin film solar cells, copper indium gallium selenide thin film solar cells (CIGS), and cadmium telluride thin film solar cells.
