PRAMAC Swiss SA, part of the PRAMAC multinational group, began producing thin film solar panels in July 2009. Their plant, based in Riazzino, is the largest solar panel production facility in Switzerland. It produces Micromorph® panels that use multi-layer thin film technology: active hydrogenated silicon layers (Si:H) and transparent conductive oxide (TCO) contact layers are deposited on a glass substrate by chemical vapour deposition. This layered technology increases absorption in the near-infrared and significantly increases efficiency.
