With CIGS' potential for being produced using a low-cost, roll-to-roll manufacturing process, it has quickly become one of the most promising thin-film photovoltaic technologies. One of the leaders on nanoparticle ink technology for CIGS is www.nanosolar.com
However, similar to cadmium telluride (CdTe) cells, CIGS is also sensitive to moisture and oxygen. Commercially available flexible CIGS solar cells only have a guaranteed lifetime of two to three years because testing shows that their efficiencies degrade quickly in high-temperature and high-humidity environments.
