CIS: Superior in performance, efficiency and environmental impact

CIS stands for the elements copper (C), indium (I) and selenium (S), which are the materials on which Solar Frontier’s CIS technology is based. CIS is currently regarded as the most innovative technology associated with the serial production of solar modules and offers advantages in terms of power generation, efficiency and environmental impact.

The higher energy yield compared with conventional crystalline silicon modules is one of a number of significant advantages offered by the Solar Frontier PowerModules. Solar Frontier’s CIS technology is also more efficient than other thin-film modules such as tandem, amorphous or microamorphous modules.

Many model calculations for solar power installations based on conventional module technologies assume optimum conditions, with the sun high in the sky, no clouds, a clear atmosphere, no shadows, moderate temperatures. But for how many hours in a year are these conditions really present? With the CIS PowerModules from Solar Frontier higher power yields can be obtained more than with rival products, even in shadow, under cloudy skies, low light or high temperatures – thanks to the remarkable properties of CIS technology:

Another advantage, not only in comparison with crystalline modules but also with other-thin film technologies, such as cadmium tellurite, is the low environmental impact of CIS technology. Solar Frontier modules are free from lead and cadmium, and thus satisfy the requirements of the Restriction of Hazardous Substances (RoHS) directive. The substantially lower percentage of raw materials required for manufacturing Solar Frontier’s CIS PowerModules highlights the more environmentally friendly nature of the technology and its production processes.
