Thin-Film Solar Manufacturers

Many companies are using thin-film technology to produce low-cost solar panels. The technology is from nanotechnology that produces solar ink. The technology is then licensed to production companies.

The cost reduction comes from a new, continuous manufacturing process which uses cadmium telluride thin film rather than the more expensive crystalline silicon. Non-silicon semiconductor materials including copper, indium, gallium and selenium (CIGS) used to create photovoltaic cells
