A photovoltaic solar module is a set of electrically connected solar cells. Its purpose is the generation of electric current. Solar cells can be manufactured from different materials. Mostly mono-crystalline or poly-crystalline silicon is used. For thin film solar cells, thin semiconductor layers are deposited on an inert substrate, mainly glass. For the manufacturing of solar cells various equipment is necessary.
Quite often, single solar cells do not produce enough electrical power. Therefore many PV cells are combined in so called photo-voltaic solar modules and weather proof mounted between glass plates. This assembly can be done inline and fully automatic. The FGET manufacturing process consists of several steps:
