SINGULUS TECHNOLOGIES has announced the availability of VITRUM GEN 2, an advanced wet-chemical processing tool for thin film solar cells, in the US market.
The company will demonstrate the system at the Intersolar North America event. The integration of this tool with existing production lines is easy and it delivers a high cycle rate. The VITRUM GEN 2 also provides considerable cost savings.
The processing system cleans edges and back-sides of thin film solar cells simultaneously in one single step. It protects the active layer and executes rear side and pencil etching with chemicals and brushes. In addition, it is used to etch unwanted coatings present on the edges and back-sides of the solar cells.
SINGULUS TECHNOLOGIES’ advanced wet-chemical processing tool reduces CdTe or CdS production steps. CdTe manufacturing process is performed in six steps, which include glass washing, rear side cleaning of CdCl2, deposition of CdCl2 using roller, salt removal, washing of glass and developer.
The VITRUM GEN 2 allows reproducible, reliable and homogeneous etching process compared to dipping processes. Other benefits of the product include higher process speed, decreased carryover and higher etch concentration.
