Thin-film technology

When one hears about thin-film technology in the PV sector, one is usually talking about solar cells. In addition to monocrystalline solar cells and polycrystalline solar cells, there are also PV modules that are produced using the thin-film process. In this process, the material is sprayed or vapour-deposited onto a substrate. The modules usually achieve a significantly lower efficiency than their much thicker counterparts.
