Aurora Solar Technologies, Canada

About the company

Aurora Solar Technologies develops, manufactures and markets inline quality control systems for the solar cell manufacturing industry.

Aurora’s products measure and display the results of critical cell fabrication processes, revealing material properties and the performance of manufacturing tools and processes. They allow process engineers and production-line operators to rapidly detect and correct process excursions, material faults and optimize processes, thereby increasing our customers’ throughput, yield, and profit.

Aurora is a public company, headquartered in Vancouver Canada. We are listed on the TSX Venture Exchange under the symbol ACU.

Control and optimization of solar cell production start with measurement. Aurora’s DM™ products use proprietary patented technology, based on the principles of infrared spectroscopy, to measure the properties of the afore-mentioned solar cell chemical layers as they are deposited and annealed.

Aurora’s Visualize™ software then uses the real-time data provided by the DM measurement products to show the relationship between the per-wafer measurements and the changing spatial variations in chemical layer properties induced by variations in the behavior of manufacturing equipment used to create these layers. This “MRI”-like view of process tool performance provides the means to quickly and effectively perform diagnostics, control, and equipment optimization.

Aurora’s newest product, Insight™ is a “data science” package that extends their product portfolio, from measurement and characterization of equipment variation, to provide a deep understanding of the effects of these variations on finished cell efficiency. This proprietary product analyses the large volume of data available from the sequence of finished solar cells in a production line and reveals the links between unwanted variations in their efficiency and the causes in production. These analyses allow advanced cell manufacturers to know precisely when and how to control their production for optimal yield and throughput, allowing them to increase their profits.
