CIGS, CdTe and Perovskite Technology
Thin Film overview
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. With our production equipment we are one of the few companies able to equip both efficiently running factories for the manufacturing of CIS/CIGS and CdTe thin-film modules as well as single production equipment for the different manufacturing steps.
SINGULUS TECHNOLOGIES has developed and introduced machines for all relevant manufacturing steps:
- Sputtering
- Evaporation
- RTP for selenization & sulphurization
- Buffer layer deposition
- Wet-chemical cleaning
