From exploring the microscopic properties of new photovoltaic materials in university laboratories to testing dozens of solar cells per minute on large factory production lines, and then to on-site performance evaluations of photovoltaic power stations in remote areas, Beijing Saifan Optoelectronics' LED solar simulators, with their powerful scene adaptation capabilities, have become the "standard light testing equipment" for users of different scales and in various fields. This device, which embodies the essence of 20 years of optoelectronic technology, is breaking the industry limitation that "one device can only serve one type of scenario" with modular design and customized solutions.
Laboratory-exclusive: A small but precise tool for light science research
For laboratories in universities and research institutes, the accuracy and flexibility of equipment are often the top considerations. The "research-grade" configuration of the Saifan LED solar simulator perfectly meets the demands of cutting-edge research.
The micro-area testing module makes nanoscale research possible. By installing a microscopic optical system, the spot diameter can be reduced to 50μm, enabling precise testing of the photoelectric performance of local areas of photovoltaic materials. The School of Materials Science and Engineering of a certain university utilized this function to observe for the first time the abnormal light response at the grain boundaries of perovskite films, providing a brand-new perspective for solving the problem of material stability. The related results were published in Advanced Materials.
Multispectral rapid switching meets the requirements of interdisciplinary research. It supports one-click switching among 8 standard spectra such as AM0 and AM1.5G, with a switching time of only 3 seconds. It is particularly suitable for research in photocatalysis, photobiology and other fields that require comparing the effects of different spectra. A certain biological laboratory used it to study the hydrogen production efficiency of cyanobacteria under different simulated sunlight conditions. Within a week, it completed the experimental volume that would otherwise take a month with traditional equipment, significantly accelerating the research progress.
The lightweight design is suitable for the complex laboratory environment. The main unit weighs only 25 kilograms and can be easily moved into special experimental devices such as glove boxes and inert gas protection chambers. In a certain OLED material research, researchers integrated the equipment into a nitrogen protection system and successfully tested the stability of sensitive materials under simulated sunlight, avoiding the problem that traditional equipment could not enter the protection chamber due to its large size.
Pilot line adaptation: A bridge for technological transformation that connects the upper and lower levels
During the pilot production stage from laboratory achievements to mass production products, the equipment needs to have both research-level precision and initial mass production testing capabilities. The "pilot-scale" configuration of the Saifan LED solar simulator has become a key link for technological transformation.
The semi-automatic test platform balances accuracy and efficiency. Equipped with a simple mechanical arm to achieve automatic loading and unloading of samples, the testing speed can reach 10 pieces per minute, while maintaining a testing accuracy of ±0.3%. After the pilot production line of a certain new energy enterprise was introduced, it successfully completed the transition of perovskite solar cells from laboratory small-scale trials to the trial production of 100-watt-level modules, accumulating valuable data for the commissioning of the mass production line.
The expandable interface supports linkage with pilot-scale equipment. The reserved interfaces such as RS485 and Ethernet can be seamlessly integrated with pilot-scale equipment like coating machines and laser scribing machines, enabling real-time correlation between test data and production parameters. By analyzing the correlation between the two, the enterprise successfully controlled the fluctuation of the battery cell efficiency within ±0.5%, providing an important basis for the quality control of mass production.
The portable design meets the flexible testing requirements at the pilot plant site. The equipment adopts an integrated chassis, equipped with handles and rollers, and can be easily moved to different workstations in the pilot plant. During the pilot-scale production of heterojunction batteries, technicians used it to conduct on-site tests in multiple stages such as cleaning, coating, and packaging, quickly identifying the key processes that affected battery efficiency and increasing the pilot-scale yield by 20%.
Mass production line customization: The core of efficient and stable quality control
For large-scale photovoltaic enterprises, the speed, stability and maintainability of equipment directly affect production costs and product quality. The "mass production-level" configuration of Saifan LED solar simulators tailors solutions for production lines.
The fully automated testing system enables unmanned production. Deeply integrated with the production line MES system, through full-process automated design such as visual positioning, robotic arm handling, and automatic wiring, the testing speed can reach 60 cells per minute, and the test data of each battery cell is automatically uploaded to the cloud database. After a major PERC battery manufacturer introduced it, the number of personnel in the testing position decreased by 80%, and at the same time, the rework rate caused by testing errors dropped below 0.1%.
Redundant design ensures the continuous operation of the production line. The key components adopt a dual backup design. The light source module can be replaced online, and the replacement time for a single module only takes 5 minutes, ensuring that the equipment operates effectively for over 8,000 hours throughout the year. In the comparison data of a certain TOPCon battery production line, the comprehensive operating rate of Saifan's equipment reached 98.5%, which was 3 percentage points higher than the industry average.
Big data analysis functions facilitate process optimization. The system can automatically analyze massive test data, identify the production batches corresponding to the battery cells with abnormal efficiency, and trace back the key process parameters. A certain enterprise discovered through this function that when the temperature fluctuation in the PECVD process exceeded ±2℃, the battery efficiency would significantly decrease. Based on this, after optimizing the temperature control system, the rate of A-grade products increased by 4%, and the annual profit increased by more than 10 million yuan.
Outdoor applications: A tough and reliable on-site inspection expert
In the installation, commissioning and operation and maintenance assessment of photovoltaic power stations, on-site testing equipment needs to adapt to complex outdoor environments. The "outdoor-level" configuration of the Saifan LED solar simulator demonstrates a strong environmental adaptability.
The mobile design breaks through the limitations of the site. The device is integrated in a portable case, equipped with a battery and a solar charging panel, and can operate continuously for 8 hours without an external power supply. At a photovoltaic power station on a certain plateau in Qinghai Province, technicians used it to conduct on-site efficiency tests on the installed components, ensuring that the performance of each component met the design requirements and avoiding hidden damage caused by transportation and installation.
The anti-interference ability can cope with complex environments. It adopts multiple shielding technologies, maintaining testing accuracy even in strong light, high temperature and high humidity environments. In a photovoltaic project on a certain island in Hainan, the equipment operated continuously for a week in an environment with a temperature above 35℃ and a humidity of over 90%. The deviation between the test data and the laboratory data was only ±0.5%, providing a reliable basis for the performance evaluation of the power station.
The simple operation interface is convenient for on-site personnel to use. The touch interface optimized for outdoor operation scenarios simplifies the test process to just three steps, allowing even non-professionals to quickly get started. The operation and maintenance team of a certain power station stated that with this device, they can conduct on-site inspections of suspected faulty components at any time, significantly reducing the time for troubleshooting and enhancing the power generation efficiency of the power station.
