Aurora Solar Technologies Inc. products

The Decima CD measures the emitter sheet resistance within crystalline silicon photovoltaic (PV) wafers. This innovative product is the industry’s most accurate and reliable measurement tool that characterizes diffusion and annealing process results. The Decima CD measures sheet resistance at a series of discrete points along the center track of each wafer. Its patented technology provides accurate real-time measurements for process control and optimization. Each measuring head connects to Aurora’s Veritas™, a quality control system for measurement integration and operations. Veritas enables optimization of diffusion and annealing processes by providing operators and process engineers with real-time 3D visualization of intra-furnace dynamics, both spatially and by batch.

The Decima 3T accurately and reliably measures emitter sheet resistance inline at full production speeds. The sensor uses safe reflected infrared light to produce high-resolution characterization of emitter sheet resistance from edge-to-edge on a wafer.

BT Imaging offers offline and inline photoluminescence inspection equipment for PV materials including silicon, perovskite and thin film materials for use at different processing stages from ingots, as-cut wafers and cells, to solar modules. BT Imaging products are owned and actively used by the world’s top-tier manufacturers and research institutes for research purposes, test and classification, quality control, process improvement and the tuning of production lines.
