Make the Invisible Visible: From early-stage research to final production QA, you need fast, high-resolution inspection tools to optimize new cell designs, diagnose material issues, and improve yield. BrightSpot Automation provides EL/PL imaging systems, custom-engineered for silicon and thin-film technologies, to help R&D labs and factories make the invisible visible.
Find cracks, cold solder joints, soldering damage, shunts, and high series-resistance regions.
Non-contact PL imaging enables processing optimization and statistical process control by testing after texturing, diffusion, dielectric deposition, and metallization.
Versatile systems support all stages of PV development: Subcells, Cells, Mini-Modules, Full-Sized Panels.
All camera, power supply, post-processing, and analysis parameters are saved in Recipes for operator ease and consistency.
Reduce risks by sample testing incoming cells and panels – get what you paid for!
IMPEL software can be customized to handshake with factory PLCs and to communicate with secure enterprise software systems.
Get clear, detailed visualizations of defects with the highest resolution imaging in the industry.
Turn a series of EL/PL images into maps of device parameters: diode ideality factor, series resistance, and implied Voc.
To support research, product development, and production, we offer a range of standardized and customized inspection tools.
PanEL-Spot enables EL Imaging on a range of PV samples, from individual solar cells to full-size commercial panels, and everything in between. See why your cells and panels exhibit low efficiency, including defects such as cell cracks, wire soldering problems, and thin-film shunting.
Not every photovoltaic application fits inside a standard box—and we don’t expect it to. BrightSpot offers customized imaging systems for factory line and robotic integration, offline testing, varied panel orientation and shape, and tight working distance constraints.
Measure contact resistivity between the metal gridlines and the semiconductor, the line resistance of the gridlines, and sheet resistances of various conductive layers for both R&D experiments and factory QC
Control
IMPEL is the unified control platform for BrightSpot imaging systems, enabling seamless coordination of camera, light sources, and power supply. From a single interface, users can adjust exposure settings, trigger PL or EL sequences, and automate capture workflows across multiple system components.
Enhance
Built-in image processing tools help users sharpen contrast, highlight defects, and visualize subtle variations in cell or panel performance. With support for custom filters and multispectral imaging, IMPEL ensures every captured frame delivers actionable insights, whether in R&D or field diagnostics.
Report
IMPEL simplifies documentation by generating detailed reports with embedded images, metadata, and measurement context. Export results for internal QA, client acceptance, or long-term traceability – standardized and ready to share.
All our cameras are also capable of capturing high-resolution video. Make convincing electroluminescence movies to aid product development and to market the superiority of your company’s products vs the competition.
