Our EpiNex™ wafers enable higher efficiencies, lower costs and reduced carbon emissions in wafer manufacturing by more than 70% when compared with the conventional Czochralski process in regions that rely on coal-based electricity. NexWafe’s innovative and unique technology creates the opportunity to profitably manufacture ultra-low-carbon green solar wafers.
We develop a novel manufacturing process sequence for polysilicon on oxide (POLO) IBC solar cells by applying a local PECVD SiOxNy/na- Si deposition through a glass shadow mask to form the structured carrier-selective n-poly-Si emitter in a single process step.
