In 2025, the photovoltaic industry will enter the "dual competition for production efficiency" era - the daily production capacity of 240mm ultra-large components will exceed 1,000 pieces, the efficiency of perovskite tandem cells will strive to reach 35%, and the transient irradiation response requirements of aerospace photovoltaic systems will reach the microsecond level. The industry faces three core pain points: the detection of a single component by stable equipment takes 6 minutes, which cannot meet the "second-level detection" requirements of the production line; the ultraviolet band of LED simulators is missing, making it difficult to capture the transient attenuation characteristics of new types of batteries such as perovskite; imported pulse equipment not only has a unit price exceeding 130,000 yuan (such as the government procurement price of a certain brand's pulse simulator is 1.46 million yuan), but also has a fixed pulse width, a customization cycle of over 3 months, and a delayed after-sales response, becoming the "efficiency bottleneck" that restricts the acceleration of high-end manufacturing.
Beijing Saifan Optoelectronics has been deeply engaged in optical detection for 22 years. It has directly addressed the three major industry pain points of "slow detection, inaccurate transient measurement, and difficult customization". After a two-year technical breakthrough, it has launched the SS-P8000 series of 3A-level pulsed solar light simulators - with "microsecond-level transient true light, ultra-high-speed detection, and flexible adaptation in all scenarios" as the three core breakthroughs, it has redefined the standard of pulsed solar simulation technology, and has become the "fastest and most accurate detection benchmark" for photovoltaic production lines, scientific research transient tests, and aerospace-level calibration.
I. Technological Revolution: Three Core Breakthroughs, Reconstructing the Boundaries of Pulse Simulation Technology
The Sivang SS-P8000 series breaks through the traditional design limitations of pulse equipment, which are characterized by "single mode and insufficient accuracy". It achieves a revolutionary innovation for high-end scenarios, maximizing the "efficiency + precision" advantages of pulse technology:
Microsecond-level transient true light: adjustable within 10 - 1000 μs, meeting all 3A standards
The system adopts a space-grade high-pressure pulsed xenon light source, combined with the independently developed "Pulse Energy Precise Control System". The pulse width can be adjusted continuously within the range of 10-1000 μs, perfectly matching the transient response characteristics of different types of photovoltaic devices. The spectral coverage is from 300 to 1800 nm, with a spectral matching coefficient of 0.82-1.18 (far exceeding the IEC 60904-9 3A standard). The energy proportion in the ultraviolet band (300-400 nm) precisely matches natural sunlight, enabling the accurate capture of the transient separation and recombination processes of photogenerated carriers in perovskite cells. After calibration by the national photovoltaic measurement station, the conversion efficiency measurement error is ≤ ±0.9%, and the short-term light intensity stability is ≤ ±0.3%. The data can be directly connected to international certification systems such as TÜV and UL.
Ultra-fast detection: Single component 0.3 seconds, efficiency increased by 20 times
Break through the "slow scan" bottleneck of traditional steady-state equipment, and complete the collection of all parameters of the IV curve with a single pulse. The detection time for a single 240mm large-sized component is only 0.3 seconds, which is 20 times more efficient than steady-state equipment and 3 times faster than ordinary pulse equipment. Equipped with "multi-channel synchronous acquisition technology", it can simultaneously connect 8 digital source meters, supporting continuous "flow-line" detection on the component production line. The daily detection volume can reach over 100,000 pieces, perfectly meeting the core needs of photovoltaic enterprises for "increasing production and improving efficiency". In pulse mode, there is no continuous heating due to light exposure, and the temperature rise in the detection area is ≤ 1℃, avoiding performance drift caused by high temperatures of the components. This is especially suitable for testing temperature-sensitive devices such as perovskite and flexible thin films.
Flexible adaptation for all scenarios: extensive coverage + modular customization, with a cycle of only 30 days
The innovative design adopts "array-type optical layout", and the irradiation surface can be flexibly customized (from Φ200mm to 1200×1500mm). The uniformity across the entire area is ≤1.8%, and the deviation between the edge and the center light intensity is ≤0.5%. It can fully meet the detection requirements for 240mm large-sized components and aerospace solar panels. It supports rapid switching of multiple standards such as AM1.5G and AM0, and the light intensity can be precisely adjusted within the range of 0.1-1.2S0. It adopts a modular design, and can be customized with special functions such as "transient attenuation test, dynamic light intensity simulation, and vacuum environment adaptation" according to the scene requirements. The customization cycle is only 30 days, which is much faster than the 3 months of imported equipment.
II. Scene Deepening: Three High-End Domains, Becoming Irreplaceable Core Equipment
The Sifan SS-P8000 series, leveraging the advantages of "high speed + precision + flexibility", has achieved in-depth penetration in three major high-end fields and has become a benchmark case in the industry:
Photovoltaic production line: Ultra-fast detection, production capacity increased by 30%
A leading photovoltaic enterprise has applied the SS-P8000 to the production line of 240mm modules, achieving an ultra-high-speed continuous detection rate of "0.3 seconds per piece". The daily detection volume has increased from the original 30,000 pieces to 100,000 pieces, with a capacity increase of 30%. The equipment can automatically identify defects such as hidden cracks and broken ribs in the modules, and the accuracy rate of defective product identification reaches 99.7%. The defective product rate at the factory has been reduced from 0.2% to 0.05%, resulting in annual savings of over 6 million yuan. Compared with imported pulse detection lines, the equipment procurement cost has been reduced by 50%, and the annual maintenance cost is only 1/4 of that of imported equipment.
Research transient testing: Capturing microscopic mechanisms, facilitating technological breakthroughs
The Photovoltaic Materials Laboratory of Zhejiang University selected SS-P8000 and, through its 10μs narrow pulse mode, successfully captured the transient migration process of photogenerated carriers in perovskite/TOPCon stacked cell, clarifying the mechanism of the influence of interface layer optimization on carrier lifetime. The related research results were published in "Advanced Materials". A certain university utilized its adjustable pulse width function to conduct research on the transient photoelectric response of dye-sensitized solar cells. The experimental period was shortened by 40% and the data repeatability reached 98%.
Astronautical-grade calibration: Adapted to extreme environments, ensuring precise on-orbit performance
The Institute of Space Technology of the Chinese Academy of Sciences selected the customized SS-P8000 (suitable for vacuum / high-low temperature environments) to conduct transient irradiation calibration for a new type of satellite solar sail panel. It simulated the AM0 spectrum and pulsed irradiation environment in space. The equipment maintained an irradiation stability of ≤ ± 0.5% within the extreme temperature range of - 50℃ to 90℃, successfully verifying the transient power generation performance of the sail panel under complex space lighting conditions. In the testing of the photovoltaic system of the Mars probe, its adjustable pulsed energy and spectral range perfectly simulated the sunlight characteristics under the thin atmosphere of the Martian surface, providing reliable data support for in-orbit performance prediction.
III. Brand Value: Domestic Replacement, Re-defining the Service Standards for Pulse Equipment
