Classification of solar glass
Depending on their properties and manufacturing methods, photovoltaic glass can be categorized into three main types: cover plates for flat-panel solar cells, usually made of rolled glass; thin-film solar cell conductive substrates, coated with semiconductor materials typically just a few micrometers thick on the surface of flat glass; and glass lenses or reflectors used in concentrating photovoltaic systems.
