Full-link Intelligent Inspection Empowers Industrialization｜Aijiang Tech’s Integrated Inspection Solution for Tandem Perovskite Solar Cells

Driven by the dual-carbon goals, tandem perovskite solar cells have emerged as a core track for photovoltaic industry upgrading thanks to their ultra-high conversion efficiency. Nevertheless, tandem cells feature sophisticated structures and rapid R&D iterations. Strict requirements are imposed on detection precision and data traceability throughout material R&D, device fabrication, mass-production manufacturing and end-of-life power-station operation & maintenance. Conventional inspection approaches struggle to balance lab-scale characterization and mass-production quality control, hindering the commercialization of this technology. To address industry pain points, Wuhan Aijiang Technology has rolled out an end-to-end integrated inspection solution for tandem perovskite solar cells. It connects lab-based R&D, factory mass production and on-site power-station operation, underpinning the industrialization of tandem perovskite technologies.

As a national high-tech enterprise and Hubei-province-level “Specialized, Refined, Differential & Innovative” enterprise, Aijiang Technology has long focused on high-end precision industrial intelligent inspection. The company holds more than 120 patents and has obtained authoritative certifications including ISO9001 and CE. Leveraging its self-developed Xinghan AI large-scale data model, Aijiang has built a complete ecosystem covering inspection instruments, intelligent equipment and industry-oriented solutions, with products and services delivered to over 30 countries and regions worldwide. Complying strictly with IEC standards, JJF metrological specifications, local and group industry standards, the newly launched tandem perovskite inspection solution satisfies multiple scenarios including R&D validation, mass-production quality control and O&M inspection, enabling closed-loop management of the full inspection workflow.

At the laboratory R&D stage, the solution incorporates professional instruments such as PL/EL imagers, QE spectral testing equipment and steady-state photoelectric test setups, including the Quantum Efficiency (QE) Tester, EL/PL Integrated Tester and APS-400C Solar Simulator. It delivers accurate characterization of material properties, captures authentic photoelectric parameters of solar cells for researchers and supports efficient process iteration and optimization. It mitigates test distortion challenges triggered by perovskite hysteresis effects and lightinduced degradation.

For large-scale manufacturing lines, the solution deploys the APS-1000C LED-based steady-state solar simulator paired with the ALB-1000C light soaking unit. It realizes AM1.5G standard spectral matching and high-uniformity irradiance output to support response-characteristic and light-stability testing. Integrated inline film-thickness measurement and AI-powered visual defect-recognition equipment leverage multimodal AI algorithms to identify hidden defects such as thin-film pinholes and interfacial flaws in real time for in-process production control. Supported by an AI-driven intelligent data platform, inter-device data interoperability is achieved, allowing full defect traceability and iterative process optimization. This effectively boosts production yield and cuts inspection costs.

For downstream utility-scale power-station scenarios, the solution deploys AI-enabled EL-inspection UAVs for photovoltaic power plants as well as portable EL testers. It performs on-site operational inspection and addresses component degradation assessment, ensuring reliable power generation in field conditions.

Boasting core strengths including multimodal AI inspection, high-precision algorithm-driven identification, full-process traceability, interoperable userfriendly data systems and customizable services, the patent-rich solution delivers comprehensive inspection services for research institutes, adapts to retrofitting of industrial mass-production lines, and fulfills on-site testing requirements for power-station O&M.

Tandem perovskite technology is now at a critical transition point from laboratory R&D toward large-scale manufacturing, where robust inspection capacity serves as a cornerstone for industrial roll-out. Centered on intelligent inspection, Aijiang Technology keeps refining domestically-developed inspection technologies to deliver simpler, more efficient testing workflows. The company aims to advance breakthroughs in tandem perovskite photovoltaic technologies and foster high-quality development of the new-energy industry.
