This solution delivers all-round, high-precision testing support for the crystalline silicon solar cell sector, enabling enterprises and research institutions to accelerate their progress on the path of high-efficiency cell R&D.

A Full-Process Testing System, Seamlessly Covering All R&D Stages

Aijiang Technology’s solution builds a full-process testing system spanning from material incoming inspection to reliability verification. At the material incoming stage, core technologies including microwave photoconductance decay (μ-PCD) minority carrier lifetime testing, ellipsometric film characterization, and SEM microstructure observation are integrated to accurately control key parameters such as silicon wafer purity, doping concentration and film thickness, laying a solid foundation for subsequent cell fabrication.

During the structural fabrication stage, the solution enables detailed analysis of the cell's microstructure to ensure the rationality of structural design. In the performance evaluation stage, advanced equipment such as AAA-class solar simulators combined with IV test systems and quantum efficiency testers are adopted to achieve high-precision quantitative analysis of core optoelectronic performance indicators including conversion efficiency and spectral response. Meanwhile, the application of infrared thermal imaging technology allows for accurate positioning of potential defects such as microcracks and cold soldering, safeguarding cell quality and performance.

To meet the demand for reliability verification, the solution is equipped with supporting equipment such as high-low temperature damp heat test chambers and ultraviolet aging test chambers, which simulate cell stability under extreme environmental conditions and provide reliable data support for the evaluation of long-term service performance. It can easily cope with stringent tests such as thermal cycling, damp heat, and ultraviolet aging, ensuring the stable operation of cells in various complex environments.

Strict Adherence to Industry Standards, Authoritative and Traceable Data

Aijiang Technology’s solution strictly complies with and even exceeds a series of domestic and international industry standards, including the IEC 60904 series, JJF 2129—2024, and DB35/T 2143—2023. These standards cover multiple aspects such as the measurement of photovoltaic current-voltage characteristics, requirements for photovoltaic reference devices, and procedures for establishing calibration traceability, ensuring the authority and reliability of test data.

Throughout the testing process, the solution achieves full data traceability. Every step, from raw data collection to final report generation, is recorded and backed up in detail. This not only facilitates in-depth analysis of test results by researchers but also meets enterprises’ stringent requirements for quality control and compliance. At the same time, the high repeatability of data provides a strong guarantee for comparative experiments and data analysis in the R&D process, accelerating the transformation of R&D achievements into industrial applications.
