Future Cell Concepts: TOPCon Solar Cells
SINGULUS TECHNOLOGIES provides technology solutions for both crystalline and thin-film highperformance solar cell platforms.
Tunnel oxide passivated contacts (TOPCon Solar Cells) are based on an ultrathin tunnel oxide capped by a doped Si film exhibiting excellent passivation and contact properties. This cell design has so far resulted in efficiencies of up to 25.7 %.
SINGULUS TECHNOLOGIES is an established equipment supplier with customers producing crystalline and CIGS/CdTe solar cells. SINGULUS TECHNOLOGIES cooperates with cell manufacturers worldwide and develops processes, which improve the efficiency of solar cells and at the same time reduce production costs. Evolutionary improvement in cell concepts like PERC - HJT – TOPCon – Tandem will drive the future of crystalline solar. SINGULUS TECHNOLOGIES’ expertise includes vacuum thin-film coating (PECVD, physical vapor deposition (PVD), evaporation), surface engineering, wet chemical processes and thermal processing.

Inline Wet Process Equipment
SINGULUS TECHNOLOGIES provides for the production of TOPCon high performance solar cells the important manufacturing steps: inline wet processing and vacuum deposition (PVD & PECVD). TOPCon Solar Cells
LINEX Inline Wet Process Equipment SINGULUS TECHNOLOGIES provides complete automated dry-in/dry-out solutions for wet-chemical treatment of Si-wafers in standard high-efficiency cell lines. The ongoing evolution of proven concepts in process management and the integration of innovative approaches are the basis for the development of a new generation of horizontal wet processing systems. LINEX is an inline wet processing platform with horizontal substrate transport for Si wafers. The SINGULUS TECHNOLOGIES LINEX system combines an advanced transportation system and sustainable/ innovative processing modules with proven and efficient chemical treatment. In addition to proven processes, the focus is on new applications such as single side treatment, polish etching, emitter etching and ozone applications. The highly integrated design, high throughput, high availability and low breakage rates make LINEX very attractive for solar cell manufacturers worldwide.
