Aijiang Technology’s Full-Chain Testing Solution for Aerospace Solar Cell Production Lines

Every successful launch and stable operation of aerospace vehicles in the vast universe hinges on the robust support of core energy systems. As the "energy heart" of aerospace vehicles, aerospace solar cell arrays directly determine the success or failure of missions with their performance and reliability. Faced with the stringent challenges posed by extreme space environments and the dual demands of mass production for efficiency and quality, Aijiang Technology has delved deep into industry pain points and launched a full-chain testing solution for aerospace solar cell/module production lines covering "materials → chips → modules → arrays". Leveraging intelligent technologies and high-reliability guarantees, the solution injects strong impetus into the high-quality development of the aerospace energy industry.

Deep Integration of the Full Chain, Forging a Solid Testing Defense for Production Lines

The manufacturing process of aerospace solar cell arrays is sophisticated and precise, and quality control at every stage is critical to the performance and service life of the final products. Aijiang Technology's testing solution is deeply embedded in all key process nodes of the production line, forming a closed-loop full-process testing system from the source to the end.

After the fabrication of gallium arsenide wafers, the solution uses professional testing equipment to identify potential material defects in advance. Following processes such as wafer dicing and polishing, and epitaxial growth of semiconductor layers, the PL testing of solar cell semi-finished products accurately detects crystal structure issues. Upon the completion of photolithography of electrode patterns and processes of etching + metal electrode plating, EL and IV testing are conducted sequentially to comprehensively evaluate the electrical performance and appearance quality of solar cells. Targeted testing methods are also equipped in the subsequent processes of solar cell series welding and lamination, as well as module lamination and packaging, ensuring that each batch of products meets the application standards for aerospace grade.

This full-chain integrated testing model breaks the limitation of the disconnection between traditional testing and production processes, enabling the early detection and handling of quality issues. It provides a solid guarantee for customers to mass-produce high-efficiency and high-quality aerospace solar cell with high efficiency.

Guided by Authoritative Standards, Empowered by High-performance Core Products

As a professional solution provider in the field of aerospace solar cell testing, Aijiang Technology has always taken authoritative standards as the benchmark for R&D and services. All indicators of the solution exceed the requirements of national standards such as GB/T 6494-2017 Test Methods for Electrical Performance of Space Solar Cells, GB/T 38200-2019 Test Methods for Quantum Efficiency of Solar Cells, and GB/T 6496-2017 Calibration Methods for Space Solar Cells. Moreover, the solution has been calibrated by national metrological institutes, ensuring the accuracy and credibility of testing results.

Backed by profound technical accumulation and innovative R&D capabilities, Aijiang Technology has developed a series of core testing equipment to provide solid support for the implementation of the solution. The Space Solar Cell IV Tester accurately captures the current-voltage characteristic curves of solar cells with high-precision measurement technology, fully reflecting electrical performance parameters. The Space Solar Cell EL/PL Integrated Tester integrates electroluminescence and photoluminescence testing functions, rapidly locating internal defects and microcracks in batteries to provide data support for process optimization. The Dual-light-source Steady-state Solar Simulator and AM0 High-magnification Solar Simulator precisely simulate the solar spectrum and irradiation intensity in the space environment, offering real and reliable environmental conditions for solar cell performance testing. The Large-area Space Solar Cell Array IV Tester is tailor-made for ultra-large format array products, enabling efficient and accurate overall performance testing to meet the production needs of different scales.

Five Core Advantages, Setting a New Benchmark for Aerospace Testing

Compared with traditional testing solutions, Aijiang Technology's testing solution for aerospace solar cell production lines boasts five core advantages, fully meeting the stringent requirements of the aerospace field.

First, ultimate precision and stability. All testing indicators of the solution surpass the requirements of aerospace-grade standards. With high-precision sensors and advanced data processing algorithms, it ensures the stability and repeatability of testing results, and can accurately output reliable data even in complex environments, providing a strong basis for product quality judgment.

Second, customized characteristic adaptation. The solution focuses deeply on the characteristics of gallium arsenide materials, and addresses core industry pain points such as crystal defects and radiation attenuation in a targeted manner. Through customized testing processes and parameter settings, testing is more aligned with the intrinsic properties of materials, effectively improving the long-term reliability of products.

Third, ultra-wide applicability. Breaking the size limitations of traditional equipment on testing, it can flexibly adapt to the full-size testing needs from small solar cells to ultra-large format space solar cell arrays, satisfying the diverse production scenarios of different customers.

Fourth, intelligent data traceability. Based on the MES system, a full-process data collection system is built, and an exclusive "identity code" is established for each batch of products, enabling one-code traceability from raw material procurement, production and processing to finished product delivery. It allows for the rapid traceback of full-process data and accurate location of the source of problems, providing data support for process improvement and enhancing production management efficiency.

Fifth, localized full-life-cycle services. Relying on a localized technical team, the company provides full-life-cycle services ranging from solution design, equipment installation and commissioning to personnel training. Professional technicians go deep into customers' production sites, optimize the details of the solution according to actual needs, and respond to customers' inquiries and demands in a timely manner, ensuring the stable operation of equipment and the efficient implementation of the solution, and relieving customers of all worries.

Customized Service Process, Ensuring Worry-free Cooperation Throughout the Whole Process

To meet the personalized needs of different customers, Aijiang Technology has established a standardized customized service process. After customers initiate demands by consulting the customer service team, the professional technical team will conduct in-depth technical communication at the first time to fully understand the customers' production scale, process characteristics and testing requirements. Based on the communication results, an exclusive testing solution is tailor-designed, and equipment production and solution implementation are launched upon mutual confirmation. After equipment delivery, professional commissioning and training services are provided to ensure that the customer's operating personnel master the skills of equipment use and maintenance proficiently. Finally, after the completion of delivery and acceptance, high-quality after-sales services are continuously provided to solve various problems encountered by customers in the use process in a timely manner, escorting worry-free cooperation throughout the whole process.
