CaliSolar has developed a proprietary approach to using “dirty†metallurgical grade silicon to make high quality solar cells.
Upgraded Metallurgical Silicon (UMG Si) is substantially less expensive than the electronic grade silicon usually used to make solar cells. Since the company’s founding, we have developed our ingot, wafer and cell processes to the point where we are producing cells demonstrating marketable levels of efficiency using UMG Si.
