Imaging for PV R&D and Manufacturing

Accelerate innovation and ensure quality with advanced EL and PL tools for every stage of your PV development and production.

BrightSpot customized an EL/PL system for us with a chuck for probing the busbars of large-area Si cells, and two different wavelength PL excitation lamps. The system is very helpful in optimizing our cell processing and designs. -

Make the invisible visible

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.

Reveal Hidden Defects

Find cracks, cold solder joints, soldering damage, shunts, and high series-resistance regions.

Test After Each Processing Step

Non-contact PL imaging enables processing optimization and statistical process control by testing after texturing, diffusion, dielectric deposition, and metallization.

Inspect Areas from mm² to m²

Versatile systems support all stages of PV development: Subcells, Cells, Mini-Modules, Full-Sized Panels.

Recipe-Driven Workflows

All camera, power supply, post-processing, and analysis parameters are saved in Recipes for operator ease and consistency.

Incoming Component QA Testing

Reduce risks by sample testing incoming cells and panels – get what you paid for!

Integrate with Factory Automation

IMPEL software can be customized to handshake with factory PLCs and to communicate with secure enterprise software systems.

Capture High-Resolution EL/PL Images

 Get clear, detailed visualizations of defects with the highest resolution imaging in the industry.

Perform Quantitative Mapping

Turn a series of EL/PL images into maps of device parameters: diode ideality factor, series resistance, and implied Voc. 

Imaging Tools for R&D and Manufacturing

To support research, product development, and production, we offer a range of standardized and customized inspection tools.

BrightSpot supplied Create Energy with a customized, low-cost Electroluminescence system that is central to our solar panel quality control efforts. They provided great support to get the system up and going, and it yields clear images with easy-to-use software.

IMPEL Software

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.
