BT Imaging’s inspection systems use a proprietary photoluminescence imaging technology. With applications across the PV manufacturing supply chain, their systems enable yield and cell efficiency gains for PV manufacturing lines. BTi’s products enable PV manufacturers throughout the supply chain to maximize their profits and reduce manufacturing cost via assessment of material and process quality. Resulting data and knowledge can be used to effectively predict cell performance, identify process faults, and enable process control and yield maximisation.

Existing production-line inspection techniques for wafers are performed only late in the manufacturing process when current-voltage characteristics of each complete cell can be measured using contacting instruments. Costs could be significantly lowered and product quality enhanced if inspections were possible throughout the production process.

The company offers manual tools for the laboratory and fast automated tools for production, with expertise in ingot/block manufacturing inspection as well as wafer grading.

BT Imaging’s Founders Thorsten Trupke and Robert Bardos received the prestigious 2019 Clunies Ross Innovation Award.

In 2022 BT-Imaging merged with Canadian start-up Aurora Solar Technologies, a company developing, manufacturing and marketing material inspection and inline quality control systems for the solar polysilicon, wafer, cell and module manufacturing industries.
