CIS stands for the elements copper (Cu), indium (In), and selenium (Se). In coating processes borrowed from glass production, AVANCIS applies these materials in a layer construction of around 2 µm. Two thousandths of a millimeter is all it takes to absorb sunlight. That's an outstanding performance that defies comparison.
EFFICIENCY - OUR OBLIGATION.
Studies by the National Renewable Energy Laboratory (NREL) show that CIS is the most efficient thin film technology. CIS has already attained efficiency levels of around 20% in the lab, comparable to the efficiency of multi-crystalline silicon cells.
CIS IN LOW LIGHT CONDITIONS.
Because CIS modules use a relatively broad spectrum of light, and because we make extremely low-defect layers in our production process, we achieve a high energy yield even in poor weather conditions and with low light levels. So even when the light is low, the technology is still very cost-effective.
