Amorphous modules:

For these solar modules, thin layers of photo-active semi-conductors are applied onto a substrate, usually glass. This is done by means of various methods, such as vapour deposition, sputtering (sputter process) or electrolytic baths. For this, amorphous silicon, such as copper indium diselenide (CI) or also cadmium telluride (CdTe) is used as semi-conductor material.
