In 2025, the iterative advancement of high-efficiency photovoltaic technology will enter the "deep waters" - perovskite tandem cells will aim for an efficiency of 35%, 240mm ultra-large components will be mass-produced, and the aerospace photovoltaic system will undergo rigorous environmental verification. The industry's requirements for detection equipment have risen from "meeting standards" to "guaranteeing accuracy": LED simulators lack the ultraviolet/infrared bands, unable to reproduce the full spectrum characteristics of natural sunlight, resulting in distorted accelerated aging test data; ordinary xenon lamp equipment has a uniformity deviation of over 3% in scenes larger than 1500mm, making it difficult to meet the strict requirements of third-party certifications; while imported high-end xenon lamp equipment is not only expensive (single unit over 2 million yuan), but also has a customization cycle of up to 6 months, with delayed after-sales response, becoming a "hidden barrier" that hinders the upgrading of China's high-end manufacturing.
Beijing Saifan Optoelectronics has been deeply engaged in photovoltaic detection for 22 years, directly addressing the "difficulties in simulating true light, covering large areas, and achieving high-end customization" of the industry. After three years of technical breakthroughs, it has launched the SS-9000 Pro series of large-area 3A level xenon lamp steady-state solar simulators - with "full-spectrum true light restoration, ultra-large area precise coverage, and millisecond-level dynamic response" as three technological revolutions, redefining the standards for high-end solar simulation equipment, and becoming a "true light benchmark" for scientific research breakthroughs, certification compliance, and aerospace-level applications.
1. Technological Revolution: Three Core Breakthroughs, Reconstructing the Boundary of Xenon Lamp Simulation Technology
Saifan SS-9000 Pro breaks away from the design logic of traditional equipment, achieving disruptive innovation for high-end scene pain points, allowing the full-spectrum advantages of xenon lamps to be maximized:
True light-level full-spectrum restoration: 280-2500nm ultra-wide coverage, matching degree 0.85-1.15
Using aerospace-grade 1800W high-pressure air-cooled xenon lamps, combined with the independently developed "multi-band precise filtering system", the spectral coverage ranges from deep ultraviolet (280nm) to mid-infrared (2500nm), perfectly replicating multiple standards such as AM1.5G and AM0, with a spectral matching coefficient stable at 0.85-1.15 (far exceeding IEC 60904-9 3A standards). Compared to traditional xenon lamps, the energy ratio of the ultraviolet band (280-400nm) is precisely matched to natural sunlight (about 5%), and the infrared band (700-2500nm) is continuous without breaks, capable of truly simulating extreme sunlight environments such as plateaus and deserts, solving detection requirements that "pseudo-spectrum" equipment cannot fulfill for calcium phosphate cell ultraviolet attenuation testing and aerospace component space irradiation simulation, as measured by German TÜV Rheinland, the conversion efficiency measurement error is ≤ ±0.8%, the lowest in the world.
Ultra-large area uniform control: 2000×2500mm extreme coverage, uniformity ≤ 1.5%
Innovatively adopts "three-dimensional stereoscopic uniform light technology", through 12 independent optical modules and AI algorithms to dynamically adjust the optical path, achieving a maximum 2000×2500mm irradiation surface (able to cover the entire plate 240mm component + aerospace solar panels), with uniformity ≤ 1.5% in the entire area, edge and center light intensity deviation ≤ 0.3%. Equipped with "dual closed-loop control light system", real-time monitoring of light intensity fluctuations and millisecond-level correction, continuous operation for 100 hours of irradiation stability ≤ ±0.3%/h, completely solving the industry's persistent problem of "edge data distortion, long-term drift" in large-area scenarios.
Millisecond-level dynamic response + modular customization: Adapted to extreme testing scenarios
Breaking through the traditional xenon lamp "steady-state single mode", supporting rapid switching of light intensity from 0.1-10S0 (response time ≤ 5ms), capable of simulating cloud cover, sudden changes in sunlight, etc., providing precise light sources for the dynamic performance testing of photovoltaic components; With a modular design, the spectral range, irradiation area, and testing mode can be deeply customized - the research scene can be extended to the deep ultraviolet / far infrared band, the industrial scene can integrate an online detection assembly line, and the aerospace scene can be adapted to vacuum / high-low temperature environments. The customization cycle only takes 45 days, which is much faster than the 6 months of imported equipment.
II. Deeply Focused on Scenarios: Four High-end Fields, Becoming Irreplaceable Core Equipment
The SS-9000 Pro of Saifan, relying on the advantages of "true light + large surface + customization", has achieved deep penetration in four high-end fields and become a benchmark case in the industry:
Perovskite tandem battery research: The "true light tool" for studying the ultraviolet attenuation mechanism
Nanjing University's Photovoltaic Materials Laboratory selected SS-9000 Pro and successfully captured the efficiency attenuation curves of perovskite / TOPCon tandem batteries under different ultraviolet intensities through its precise ultraviolet band control, clarifying the mechanism of the influence of ultraviolet light on interface charge transfer, and the related research results were published in "Nature Energy"; a leading battery enterprise used its 2000×2500mm large surface advantage to achieve one-time molding testing of 1.2m×2.4m large-sized perovskite components, avoiding splicing errors, and the pilot line efficiency increased by 2.3%.
Third-party certification: The globally recognized "standard light source"
12 domestic and foreign authoritative testing institutions, including Beijing Jianheng and Swiss SGS, regarded SS-9000 Pro as the benchmark equipment for high-end component certification, and their testing data were directly accepted by international certification systems such as TÜV, UL, and CE. The component certification completed by a photovoltaic enterprise using this equipment reduced the testing cycle by 40% and reduced costs by 30% when exporting to the EU; for dual-sided component certification, the equipment supports synchronous / asynchronous irradiation adjustment, can precisely simulate the ground reflection rate, and the detection data has a deviation of ≤1% compared to outdoor measurement.
Aerospace-grade photovoltaic system verification: "Simulation Chamber" for extreme environments
The Chinese Academy of Space Technology selected the customized version of SS-9000 Pro (compatible with vacuum / high-low temperature environments) to conduct ground irradiation tests for the solar panel of Chang'e 7 probe, simulating the AM0 spectrum of the lunar surface and extreme temperature changes. The equipment maintained ≤±0.5% irradiation stability in the range of -40℃ to 85℃, ensuring that the solar panel's in-orbit power generation efficiency met the standards; in the testing of the photovoltaic system of the Mars probe, its adjustable infrared band proportion successfully simulated the sunlight environment under the thin atmosphere of the Martian surface.
Cross-border photovoltaic catalysis and new energy: "Precise Light Source" in multiple scenarios
The Department of Chemical Engineering of Tsinghua University used its full-spectrum characteristics to conduct CO₂ photocatalytic reduction experiments, precisely controlling the proportion of light energy in different wavelengths, and the catalyst conversion efficiency increased by 15%; a new energy vehicle enterprise used it for the testing of curved photovoltaic components on the vehicle roof, through three-dimensional space irradiation compensation technology, precisely measuring the power generation performance of the component under different installation angles and different light intensities, providing data support for the mass production of "mobile energy vehicles".
III. Brand Value: Domestic High-end Replacement, Re-defining Service Standards
Saifan Optoelectronics has broken the monopoly of overseas brands in the high-end solar simulator field through "technological autonomy + service upgrade":
Independent intellectual property rights: 42 core patents, no technical bottlenecks
It has 42 core patents such as xenon light source control and large surface uniform light technology, among which "three-dimensional stereoscopic uniform light technology" and "multi-band filter system" have obtained national invention patents, and the technical level is far superior to similar products; it participated in the formulation of 3 industry standards such as "Detection Methods for Large-Scale Photovoltaic Components Solar Simulators", becoming the "Chinese standard setter" for high-end detection equipment. Unmatched cost-effectiveness: Cost reduced by 60%, service upgrade without discount
Based on independent research and large-scale production, the price of SS-9000 Pro is only 40% of that of imported similar products. Core components (xenon lamp, filter) offer a 5-year warranty, with a service life exceeding 10,000 hours, and the annual maintenance cost is only 1/5 of that of imported equipment. For research institutions, a "customized leasing + technology cooperation" model is introduced to lower the threshold for using high-end equipment.
