Developer, Enabler and Supplier for CIS/CIGS and CdTe Solar Cells

Solar cells can be categorized according to the applied production process and used materials, for example in crystalline and thin-film solar cells.

In thin-film solar technology a large glass panel forms the base material, on which a relatively thin layer of 1 to 2 μm of photoactive compound is applied. Amongst others, alloys consisting of copper, indium, gallium and selenium or sulfur (CIGS), compounds of cadmium and tellurium (CdTe) or thin silicon layers are used in this process.

Due to a superior performance under low light intensities thin-film solar cells deliver electrical power already in the early morning and later evening hours or at clouded sky. In addition the panels are more tolerant against local shadowing. Also thin-film solar cells do not suffer so much in their performance at high solar panel temperatures occurring at full sun intensities. Furthermore, thin-film solar panels can be used as an architectural design element for the frontside or the roof of buildings due to their homogenous surface color and attractive visual appearance.

For CIGS cells the absorption layer is comprised of copper, indium, gallium as well as selenium and partly sulfur compounds. These thin-film cells have achieved laboratory efficiency levels of over 23 %. The efficiency of modules is in a range from 14 to 17 % depending on the module size. SINGULUS TECHNOLOGIES is increasingly consulted as a development partner for highly efficient solar cells and chosen as preferred machine supplier by leading solar cells producers for the relevant machines.

With our production equipment we are one of the few companies able to equip both efficiently running factories for the manufacturing of CIS/CIGS thin-film modules as well as single production equipment for the different manufacturing steps.

In the Solar segment SINGULUS TECHNOLOGIES is a leading supplier for new production solutions for thin-film and crystalline solar cells, offering lower production costs to increase the level of efficiency or achieve a higher level of efficiency.

SINGULUS TECHNOLOGIES has established itself in this market as a worldwide recognized machine supplier for technologies enabling a sustainable and chosen energy provision on the basis of renewable energies.
